The Boone Bait Co. Kayak bag is insulated, and more importantly, is the only bag on the market that has heat-sealed seams. This prevents brine solution from leaking and contaminating the bags’ insulation. Once contaminated, it is impossible to get the odor out of the bag. All Boone kill bags are heat sealed. The kayak bag is made with six tie downs, two handles and webbing all heat sealed to bag with superior strength. The kayak bag has a screw cap drain and bag material is 1000 denier vinyl with nylon fibers for added strength.
