Premium Insulated Fishing Kill Bags 18x36 to 30x90 - Heavy Duty Fish Storage Cooler for Saltwater & Freshwater - Made in USA by Anglers for Anglers - Perfect for Boat Fishing, Kayak Trips & Offshore Adventures

When I purchased this bag, it included a specific disclaimer the bag was totally watertight based upon the fact the seams were stitched, not molded. With that knowledge in mind, I use 4 to 6 (depending upon outside temperatures) frozen 2-liter soda bottles to chill the bag. They don't leak, melt far slower than cubed ice and are significantly lighter than several 10 lb bags of ice. I've had it full of fish and the bag works very well. I've used it on 100-plus degree days, sitting in the open on the deck, and the bag has kept fish cold all day. The double handle design allows me to carry it with one hand. The flexibility of the bag allows it to be stored in many configurations, utilizing available space rather than a rigid, conventional cooler. Rinse out the inside and the bottles with a spray bottle of soap/water, invert it to dry, re-freeze the bottles and it's ready for the next day.I'm very satisfied with this product. Reading the instructions and exercising some sense will provide anyone with years of use. I'll never bother with a bulky, hard to store cooler. I've given a couple to friends as gifts and they are as satisfied as I am.Great product. Tremendously effective if used reasonably.
