Frequently Asked Questions

Is the cooler backpack truly 100% leakproof, even when filled with ice?

Yes, absolutely. We use a fully sealed, high-quality PEVA liner combined with durable outer fabric. This construction ensures that melted ice and liquids stay securely inside, protecting your gear and keeping the interior dry and condensation-free.

How long will this backpack keep items cold or hot?

With our Temperature Lock Technology (featuring thick insulating foam), the backpack is designed to maintain temperatures for many hours—typically 6-12 hours, depending on the ambient temperature and the amount of ice/ice packs used. For best results, pre-chill your items and use high-quality ice packs.

Is the exterior material durable enough for hiking and outdoor use?

Yes. The backpack is constructed with a rugged, resistant fabric designed to withstand the abrasions and demands of hiking trails, fishing trips, and constant use on boat decks. It's built to perform in challenging environments.

How much food and drink can the backpack hold?

This cooler backpack is designed for generous capacity, easily holding a day's worth of food and beverages for a small group. It can comfortably fit approximately 24-30 standard beverage cans along with ice or ice packs.

How do I clean the interior of the cooler backpack?

The leakproof PEVA liner is extremely easy to clean. Simply wipe the interior with a damp cloth or sponge using mild soap and water. Allow the interior to air dry completely before zipping it up for storage.

    I love that I can use this for my daily commute to work (it fits a full day’s lunch perfectly) and then seamlessly transition it to a weekend beach cooler. The zippered lid pocket keeps my phone and keys separate from the ice, which is a great functional detail. It's durable, comfortable, and the capacity is spot on. Worth the investment for the quality.

    This backpack solves the two biggest cooler problems: leakage and carry comfort. The breathable mesh back prevents that horrible back sweat, and the interior liner is rock solid—it truly does not leak. I appreciate that it's easy to clean. This cooler is clearly designed by people who actually use their gear. It passed the Captain Approved test with flying colors.

    This cooler is fantastic gear that lives up to the True Sailor Ltd. standard. The leakproof liner is rock solid—it handled a full day with zero drips, and the ergonomic mesh backing makes long treks much more comfortable.

    The only slight drawback is the external storage. While the capacity is good, once you pack in ice and provisions, it feels a bit snug. I wish the outer mesh pockets were slightly deeper to hold a larger water bottle more securely.

    It’s definitely Captain Approved for quality and cooling power.
