What Stands Out

  • Main compartment holds up to two size-3600 tackle trays plus an internal slip pocket
  • Open-bottom neoprene side pocket carries a rod or combo so both hands stay free
  • Built-in plier holder, side beverage pocket and a key chain clip
  • Die-cut MOLLE panel for adding pouches
  • Padded strap with a lower mount that switches to the right or left side, plus a large quick-release buckle

What To Check

  • Sized for 3600 trays, so larger 3700 trays will not go in
  • The interior is water repellent, not waterproof
  • The main listing photo shows a bottle, pliers, rod and reel as props; those are not included

The KastKing Blowbak is a fishing sling built for the walk from the truck to the water. It is one of Amazon's top sellers in Fishing Tackle Storage Bags, and the design explains why: tackle trays in the main pocket, a rod in the side pocket, pliers on the outside, and nothing in your hands.

That last part matters more with kids along. A sling that carries the rod leaves a hand free for a small one on a muddy bank.

The Numbers That Matter

Two 3600-size trays. That is the capacity that decides what you can bring. Check your trays before you buy, because 3700 trays will not fit.

8 x 6 x 14 inches, 0.55 kg. Light and narrow enough to wear all morning along a creek. The strap's lower mount switches sides, so lefties and righties both get a comfortable carry.

600D fabric, water repellent interior. It shrugs off a splash but is not a dry bag. Anything that cannot get wet belongs in a sealed box like the Plano 3440 Waterproof Stowaway.

Who It Is For

The dad who fishes ponds, creeks and bank spots and would rather carry one sling than a hard box. Load it with trays, clip aluminum fishing pliers in the plier holder and go. If you fish from a boat and want everything in one hard case, the Plano two-tray tackle box is the simpler call.

The Short Version

A compact sling that carries two tackle trays, pliers, a drink and a rod, so the walk to the pond does not take both hands. I would pick it for a dad who fishes bank and creek spots with his kids. Know that it takes 3600 trays only and is water repellent, not waterproof.
