Frequently Asked Questions
Are soft coolers safe to use on kayaks?
Yes — soft coolers are safe for kayaks when you pick one with water-resistant materials, a secure closure, and straps to anchor it. Floating or sealed designs reduce the risk of losing gear to water, and choosing a low-profile model helps it sit securely on deck or inside a hatch.
How can I prevent leaks when using a soft cooler on the water?
Use sealed ice packs instead of loose ice, avoid overfilling, and dry the zipper/lid before stowing. Place the cooler on a flat area of the deck, secure it with straps or bungee cords, and inspect seams and zippers regularly for wear. If your cooler has a drain plug, close it while traveling and open to drain when appropriate.
How long will a soft cooler keep ice or cold drinks?
Ice retention depends on insulation thickness, cooler size, ambient temperature and how often you open it. Expect anything from several hours to a full day for mid-range and premium models; premium soft coolers with thick closed-cell foam and tight zippers will hold cold longest. Using pre-chilled contents and ample ice packs improves performance.
