Reliable Fishing insulated fish bags are made with the highest quailty material and insulation and have many great features for example, the material is mildew and UV resistant, they have a 12 inch gusseted bottom which allows them to stand on their own and hold more fish. All of the bags come with a drain plug for easy clean up and are completely collapsible for an easy stow away. Why use bulky coolers or make your fish holds stink? There is no need for that with the Reliable Fishing insulated fish bag. These bags hold more fish, alleviate smells, and are easy to clean and stow away. Because they have such high quality insulation, they are able to hold ice for days, which allows you to stay out longer knowing that your fish is fresh and safe. Because our bags are sewn/stitched, they are not designed to be 100% water tight. You may have some water that leaks at the bottom corners; but, having a little leakage is best for the long term purpose of your catch.
