10 Best Kayak Fishing Tackle Bags for 3600 and 3700 Trays (July 2026) Guide

After spending countless hours on the water testing different storage solutions, I know how frustrating it can be to find the right tackle bag for kayak fishing. The limited space on a kayak demands smart organization, and that’s where understanding best kayak fishing tackle bags for 3600 and 3700 trays becomes essential for any serious angler.

If you’re new to the terminology, 3600 and 3700 refer to standard Plano tackle tray sizes that have become the industry norm. A 3600 tray measures 11.4″ x 7.3″ x 1.8″ while a 3700 tray is larger at 14.2″ x 8.3″ x 1.9″. Most quality tackle bags are designed to fit one or both of these sizes, making tray compatibility your first consideration when shopping.

Our Top 3 Kayak Fishing Tackle Bags in 2026

Best Kayak Fishing Tackle Bags for 3600 and 3700 Trays in 2026: Quick Overview

1. KastKing Bait Boss Fishing Tackle Backpack – 43L Capacity with Rod Holders

I spent three months using the KastKing Bait Boss as my primary kayak fishing bag, and it quickly became my go-to for serious fishing trips. The 43-liter capacity is massive compared to most kayak-friendly bags, yet the backpack design keeps everything accessible when I’m seated in my kayak. The high-density Oxford fabric has held up beautifully through saltwater exposure and the occasional dunking.

What really sets this bag apart is the organization. Six PVC pockets on the front keep soft plastic lures separated and visible, while the four included tackle boxes slide easily into the main compartment. I particularly appreciate the adjustable padded partition that lets me customize the interior based on what I’m carrying that day.

The fishing rod holders on the side are genuinely useful for hands-free transport from my truck to the launch site. I’ve carried two rods comfortably, though they do stick up a bit when the bag is fully loaded. The rain cover has saved my gear more than once during unexpected squalls on the lake.

Comfort is where this backpack shines. The cushioned back support with breathable padding makes long walks to remote fishing spots much more manageable. At nearly 3 kilograms, it’s not lightweight, but the weight distribution is excellent and I never felt strained even after full-day sessions.

Best Suited For

The KastKing Bait Boss is ideal for kayak anglers who carry a lot of gear and don’t mind the extra bulk. If you fish multiple species, need to bring varied tackle selections, or frequently walk to your launch spots, this backpack delivers exceptional organization and comfort.

Who Should Avoid It

Anglers with minimal tackle needs or those fishing from smaller recreational kayaks with limited storage space might find this bag oversized. The PVC lure pockets, while convenient, have shown some wear issues with heavy daily use.

2. KastKing Karryall 3600 Tackle Bag – Best Value with Included Trays

The KastKing Karryall 3600 represents what I consider the sweet spot for kayak fishing tackle storage. During my testing, this bag proved itself as the best combination of price, functionality, and included accessories. Getting four 3600-size tackle trays in the box saves you at least $20-30 compared to buying them separately.

The 600D Oxford material with hydrophobic coating has impressed me with its water resistance. After a rainy day on the water, the contents stayed dry even when the bag sat in a wet kayak hull for hours. The rubber non-slip foot pads keep the bag from sliding around, which is crucial when you’re reaching for gear while seated.

What makes this bag particularly kayak-friendly is the wide-mouth design with double-loop zipper pulls. I can access everything quickly without fumbling, even with wet hands. The clear zippered pocket on top is perfect for identifying what’s inside each tray without opening the main compartment.

The MOLLE system on the sides allows for serious customization. I’ve attached a small first aid kit and a pliers sheath using compatible accessories. The hidden water bottle pocket with strap is a clever touch that keeps your drink secure but out of the way.

Best Suited For

This is the perfect choice for kayak anglers who want maximum value without sacrificing quality. If you’re building your tackle collection and need the trays included, or if you prefer 3600-size boxes for their compact footprint, the Karryall delivers excellent bang for your buck.

Who Should Avoid It

Anglers who need more than five tray capacity should look at larger options. The included trays have somewhat flimsy latches compared to premium Plano boxes, though they’re adequate for most uses.

3. KastKing Karryall 3700 Tackle Bag – Large Capacity for Big Trays

If you prefer the larger 3700-size trays for storing bulkier lures and more terminal tackle, the KastKing Karryall 3700 is essentially the big brother of the 3600 version. I tested both and found the 3700 offers significantly more storage while maintaining a surprisingly compact footprint for kayak use.

The main compartment swallows four included 3700 trays with room for one or two more. That’s a serious amount of tackle storage in a bag that measures just 14 inches at its widest point. For kayak anglers who fish multiple techniques and carry extensive lure selections, this capacity is a game-changer.

Thirteen pockets give you organization options beyond just the trays. I use the external pockets for tools, leaders, and frequently accessed items, while the clear zippered pocket keeps soft plastics visible and protected. The integrated pliers holder with strap is well-positioned for quick access.

The construction quality matches the smaller version with 600D Oxford material and the same hydrophobic coating. After eight days of continuous outdoor testing in varying conditions, the bag showed no signs of wear, water damage, or zipper issues.

Best Suited For

Anglers who prefer 3700-size trays for their larger capacity will love this bag. It’s perfect for gear-heavy fishermen who need extensive tackle options but still want something that fits reasonably well in a kayak storage area.

Who Should Avoid It

If you fish from a smaller kayak with very limited storage, this bag’s larger footprint might be problematic. The weight when fully loaded with six trays can also be significant for long carries.

4. KastKing Large Fishing Tackle Bag – Maximum 3600 Tray Capacity

The KastKing Large tackle bag is built for anglers who refuse to compromise on how much gear they bring. With the ability to hold eight 3600-size trays, this bag offers more capacity than most kayak anglers will ever need. I found it works best when secured in a tank well or large rear storage area.

What impressed me most is how the 42-liter capacity doesn’t feel unwieldy. The bag’s proportions keep it relatively compact despite the impressive storage. The 13 internal and external pockets mean everything has a place, from pliers to phone to extra line spools.

The 600D Oxford material with hydrophobic coating and inner PVC layer provides solid water resistance. I’ve had this bag sit in pooled water in my kayak without any moisture reaching the contents. The rubber non-slip foot pads are essential for keeping the bag in place during aggressive paddling or when leaning to set the hook.

Double-loop zipper pulls make access quick and easy, even with cold or wet hands. The MOLLE straps on the sides offer expansion options if you need to attach additional gear like a landing net holder or extra tool pouches.

Best Suited For

This is the bag for tournament anglers, guides, or anyone who genuinely needs to carry extensive tackle selections. If you fish diverse waters and never know what technique you’ll need, the eight-tray capacity ensures you’re prepared for anything.

Who Should Avoid It

Recreational anglers or those with smaller kayaks will likely find this bag excessive. Some long-term users report zipper issues after about a year of heavy use, so it may not be the best choice for daily abuse.

5. KastKing Hoss Tackle Bag – Saltwater-Ready Construction

The KastKing Hoss has earned its reputation among saltwater kayak anglers for good reason. After using this bag extensively in coastal environments, I can confirm it handles saltwater exposure better than most. The 420D rip-stop nylon with PVC inner layer and compression molded bottom creates a formidable barrier against moisture.

What sets the Hoss apart is the self-healing zippers. After months of saltwater exposure, the zippers still operate smoothly with no corrosion or sticking. For kayak anglers who regularly fish in saltwater environments, this feature alone can extend the bag’s usable life significantly.

The Neo-grip shoulder strap stays in place on your shoulder without slipping, even when wet. I’ve carried this bag fully loaded on long walks to remote launch spots without discomfort. The molded tool holder keeps pliers accessible, which is essential when you’re fighting a fish and need to cut line quickly.

With 12 internal and external storage pockets, organization is straightforward. The main compartment holds six 3600 trays with one more fitting in the front pocket. The external rubber-coated mesh pockets are perfect for items that can handle getting wet.

Best Suited For

Saltwater kayak anglers will appreciate the corrosion-resistant construction and waterproof bottom. If you fish coastal waters, brackish estuaries, or any environment where salt exposure is a concern, the Hoss is built for your needs.

Who Should Avoid It

Anglers wanting premium thick materials might find the 420D nylon lighter than expected. The fit for eight trays is tight, so if you need to carry that many, consider a larger option.

6. Baitium Fishing Backpack – Eco-Friendly with Insulated Cooler

The Baitium Fishing Backpack caught my attention for its unique insulated top pocket. This feature lets you keep bait fresh or drinks cold during long sessions on the water. I’ve used it to keep nightcrawlers lively in summer heat and found it genuinely effective for several hours.

Beyond the cooler, this is a well-designed 40-liter backpack with four 3600-size tackle trays included. The 600D Oxford fabric construction has held up well through my testing period, showing good resistance to abrasion and water exposure. For anglers who care about environmental impact, Baitium donates a portion of each purchase to ocean conservation efforts.

The rod holders are intelligently positioned for hands-free transport, keeping your rods secure while you hike to remote fishing spots. I’ve found them stable enough for two medium-weight rods without any wobbling or concern about damage.

Four water bottle pockets seem excessive until you’re out all day in hot weather. Having multiple hydration options plus the insulated cooler makes this backpack ideal for long kayak fishing sessions where staying hydrated matters as much as having the right tackle.

Best Suited For

Anglers who fish all-day sessions in warm weather will love the insulated pocket and multiple bottle holders. If you appreciate eco-conscious brands and want a full-featured backpack with included trays, the Baitium delivers.

Who Should Avoid It

Anglers who prioritize extensive internal organization might find the pocket layout limiting. Some users report the zippers feel less substantial than premium competitors.

7. Reaction Tackle Bag – Premium 1000D PVC Waterproof Construction

The Reaction Tackle Bag represents the premium end of kayak fishing tackle storage. The 1000D PVC construction is genuinely waterproof, not just water-resistant. During my testing, I accidentally dropped this bag in shallow water and the contents stayed completely dry. That level of protection matters when you’re carrying expensive reels and electronics.

The removable dividers are a standout feature for kayak anglers who need flexibility. I’ve reconfigured the interior multiple times depending on whether I’m carrying standard trays, oversized boxes, or a mix of both. The double-layer construction adds durability without excessive weight.

Multiple strap options let you carry this bag however works best for your situation. I’ve used it as a shoulder bag for short walks, a crossbody for bike rides to the launch, and handheld when loading the kayak. Each carrying style feels secure and comfortable.

The waterproof bottom means you can set this bag directly on wet surfaces without worry. On a kayak, that’s invaluable when deck space is limited and everything gets wet. The bag also features excellent customer service, which is worth noting if you ever encounter issues.

Best Suited For

Anglers who need genuine waterproof protection and premium construction quality will appreciate this bag. If you fish in consistently wet conditions or carry expensive gear that absolutely must stay dry, the 1000D PVC material justifies the higher price.

Who Should Avoid It

Budget-conscious anglers may find better value elsewhere. The small size only holds 3600 trays, not 3700, so verify the size you order matches your tray collection.

8. Pelican Exocrate Fishing Bag – Milk Crate Compatible Design

The Pelican Exocrate is designed specifically for kayak anglers who use the classic milk crate storage system. This bag slips perfectly over a standard 13×13 inch milk crate, transforming a basic plastic box into a fully-featured tackle storage system. I’ve used this setup on my fishing kayak for months and it’s become my preferred configuration.

The 1200D polyester material is noticeably thicker and more durable than the 600D fabric found on many competitors. It’s UV and saltwater resistant, which shows in how well it’s held up to coastal fishing trips. The material actually exceeds the strength of my motorcycle gear, which says something about build quality.

Two rod holders with drainage holes give you a place to stash rods when you need both hands. I use them constantly when rigging up or changing lures. The drainage prevents water from pooling, which is a thoughtful detail that prevents corrosion and mildew.

The multiple compartments around the sides are perfect for tools, pliers, and frequently accessed items. The lined storage compartment with heavy-duty zipper keeps sensitive items protected. Reflective logos add visibility for early morning or evening sessions.

Best Suited For

Kayak anglers who already use or want to try the milk crate storage system will find this bag purpose-built for their needs. If you want rod holders built into your tackle storage and need saltwater-resistant construction, the Exocrate delivers.

Who Should Avoid It

Anglers who don’t use milk crates or prefer traditional bag designs might not appreciate the form factor. The rod holders could be deeper for added security with longer rods.

9. Gonex Medium Tackle Bag – Versatile 3600 and 3700 Compatibility

The Gonex Medium Tackle Bag solves a common problem for kayak anglers with mixed tray collections. The main compartment holds four 3700-size trays while the front pocket accommodates one 3600 tray. This versatility is rare and valuable if you’ve accumulated both sizes over the years.

At just 1.89 pounds, this is one of the lightest tackle bags I’ve tested. The weight savings matters when you’re already carrying a fully-rigged kayak to the water. The high-strength anti-tear polyester with double-layer construction still manages to feel durable despite the low weight.

Eight total pockets provide solid organization options. The side pockets include pliers storage, while the net pocket and transparent inner pockets keep small items visible and accessible. The wide-mouth design with double-loop zipper makes it easy to find what you need quickly.

The HDPE water-resistant bottom is easy to clean and provides a barrier against wet kayak hulls. Three carrying options (shoulder, hand, crossbody) give you flexibility for different transport situations.

Best Suited For

Anglers with mixed 3600 and 3700 tray collections will appreciate the dual compatibility. If you want a lightweight bag that doesn’t sacrifice organization or durability, the Gonex Medium is an excellent choice.

Who Should Avoid It

As a newer product with limited reviews, some anglers may prefer more established options. Those needing full waterproof protection should look at premium alternatives.

10. Gonex Tackle Bag 3700 – Budget-Friendly 3700 Storage

The Gonex Tackle Bag 3700 proves you don’t need to spend a fortune for functional kayak fishing storage. At under $30, this bag delivers the essentials: four 3700 tray capacity, water-resistant construction, and comfortable carrying. For anglers on a budget or those just getting into kayak fishing, this is a solid starting point.

The 420D high-strength anti-tear polyester with PVC waterproof coating has impressed me with its durability. After several months of use, the material shows minimal wear despite regular exposure to sun, water, and the general abuse that comes with kayak fishing. The HDPE hard bottom is genuinely waterproof, making this bag safe to set directly in wet kayak hulls.

Multiple pockets provide decent organization for tools and accessories. The transparent PVC pocket is particularly useful for keeping your phone or wallet dry and visible. Soft shoulder pads and adjustable straps offer three carrying options: shoulder bag, hand bag, or crossbody.

The main compartment fits four 3700 boxes comfortably. While the bag doesn’t include trays, the low price leaves room in your budget to buy exactly the boxes you want. Many anglers prefer choosing their own tray configurations anyway.

Best Suited For

Budget-conscious anglers who need 3700 tray storage will find excellent value here. If you’re new to kayak fishing and want to test the waters without a major investment, this bag provides everything essential at an unbeatable price.

Who Should Avoid It

Watch out for the cheap plastic shoulder strap hooks, which can fail under heavy loads. Anglers wanting included trays or premium construction should step up to a higher-tier option.

Buying Guide: Choosing the Right Kayak Fishing Tackle Bag

When selecting a tackle bag for kayak fishing, several factors matter more than they would for shore or boat fishing. Limited space, constant water exposure, and the need for easy access while seated all influence which bag will work best for your situation. Before making a kayak fishing gear investment, consider these essential factors.

3600 vs 3700 Tray Sizes Explained

Understanding tray sizes is fundamental to choosing the right bag. The 3600 tray measures 11.4″ x 7.3″ x 1.8″ and is ideal for kayak fishing due to its compact footprint that fits easily in tight spaces. The 3700 tray measures 14.2″ x 8.3″ x 1.9″ and holds more gear per tray but requires more storage real estate.

Most bags are designed for one size or the other, though some versatile options accommodate both. If you already own trays, match your bag to your existing collection. If you’re starting fresh, 3600 trays are generally better for kayak fishing due to their smaller size, while 3700 trays work well for anglers who need maximum capacity per box.

Hard vs Soft Tackle Bags for Kayaks

Soft tackle bags are almost always better for kayak fishing. They’re lighter, more flexible for fitting in irregular spaces, and won’t damage your kayak if they shift during transport. Hard boxes provide superior protection but are bulky and less practical for kayak storage.

Many experienced kayak anglers use both: hard boxes for home storage and organization, soft bags for actual trips. This hybrid approach keeps your gear protected at home while maintaining portability on the water.

Water Resistance and Drainage Features

Water resistance is non-negotiable for kayak fishing. Look for bags with hydrophobic coatings, PVC liners, and waterproof bottoms. The bottom is especially important since your bag will likely sit in pooled water at some point.

Drainage features often get overlooked but matter significantly. Bags without proper drainage can develop mildew and keep your tackle wet for days. Look for drain holes, breathable materials, or designs that allow moisture to escape.

Kayak-Specific Features to Look For

The best kayak tackle bags include features designed specifically for the unique challenges of fishing from a small vessel. Non-slip bottoms keep your bag from sliding during aggressive paddling or fighting fish. Rod holders built into the bag free your hands for rigging and unhooking fish. Multiple carrying options (shoulder strap, handle, crossbody) accommodate different transport situations from parking lot to launch.

MOLLE systems allow customization and expansion. Kayak securing loops or attachment points let you tie down the bag to prevent loss if you capsize. Side pockets that remain accessible when the bag is wedged into tight spaces are particularly valuable.

Capacity and Organization

Consider how many trays you realistically need. Most kayak anglers do fine with 4-5 trays, though gear-heavy fishermen may want 6-8. Beyond tray capacity, look at total pocket count for organizing tools, leaders, and accessories. A bag with 10-13 pockets typically offers enough organization without becoming overwhelming.

Conclusion

Finding the right tackle bag for kayak fishing comes down to matching your specific needs with the right combination of capacity, water resistance, and kayak-friendly features. The KastKing Bait Boss Backpack stands out as our top pick for its massive 43L capacity and comprehensive organization, while the KastKing Karryall 3600 offers exceptional value with four included trays. For budget-conscious anglers, the Gonex Tackle Bag 3700 delivers essential functionality at under $30.

Whether you’re just getting started with kayak fishing or upgrading your existing storage system, the best kayak fishing tackle bags for 3600 and 3700 trays on this list have been tested and proven in real kayak fishing conditions. Match your tray size, consider your typical gear load, and choose the bag that fits your fishing style and budget.
