Maelstrom Insulated Cooler Backpack 35-Can (32L) - Leakproof, Organized Daypack with Multiple Pockets

Maelstrom’s insulated cooler backpack is a leakproof, soft-sided carry solution that keeps up to 35 cans (32L) cold or hot while organizing plates, utensils and personal items for outdoor days.

This cooler backpack blends thermal performance with thoughtful organization so you can take meals, drinks and gear to picnics, beaches, hikes or the office without dripping messes or juggling multiple bags. Built with a thick PEVA heat-sealed liner, foam insulation and a wipe-clean interior, the pack is designed to hold temperature with the help of freeze packs and to resist leaks. Multiple storage zones, ergonomic straps and a handful of built-in tools make it a practical single-bag solution for day trips.

How much can this backpack carry and how is it organized?

The Maelstrom cooler backpack offers a main insulated compartment sized to fit roughly 35 cans (32 liters) plus ice packs, with measured exterior dimensions of 12.87" x 8.97" x 18.72". Several dedicated pockets and holders keep dining gear, valuables and bottles tidy and accessible.

• Main insulated compartment for drinks and bulk food.
• Front cutlery pouch holding up to nine knives/forks and ten+ dishes.
• Top zipper pocket, front zipper pocket, hidden rear pocket and shoulder card slot for electronics, phones, cards and valuables.
• Two mesh side pockets with adjustable elastic buckles for water or wine bottles and extra straps/webbing for tools.

Will this bag actually prevent leaks and keep items cold?

The interior uses thick foam insulation plus a heat-sealed PEVA liner engineered to reduce seepage, and it’s easy to wipe clean. With freeze packs and proper packing, the insulated construction maintains chilled temperatures below 15°C for several hours; it also helps retain warmth for hot items when needed.

• High-density insulation combined with a leakproof PEVA lining.
• Heat-sealed seams to limit dripping and watery messes.
• Interior surface wipes clean quickly after spills.
• Performance depends on ambient temperature and use of ice or freeze packs.

What are the practical features for outdoor use and comfort?

Designed for activity, the Maelstrom cooler backpack adds ergonomic support and small conveniences that matter on the trail or at the park. Padded breathable back panels, S-shaped shoulder straps and an adjustable chest buckle reduce strain while an integrated bottle opener, stretch cord for sunglasses and webbing loops keep essentials within reach.

• Padded back and breathable S-shoulder straps with chest buckle for weight distribution.
• Stainless-steel bottle opener on the shoulder strap and stretch cord for sunglasses.
• Five webbing holes for hanging keys or tools and adjustable buckles to secure bottles.
• Carry handle and hidden back pocket for quick access to valuables.

How easy is it to maintain and clean?

The interior lining is made from a smooth, high-quality material that resists stains and is simple to wipe down after use. Routine cleaning requires only a damp cloth and mild soap; leave the bag open to air dry fully before storage to keep insulation and liners fresh.

• Wipe-clean PEVA interior for quick spill management.
• Durable exterior fabric resists dirt and abrasions.
• Open and air-dry after cleaning to preserve seal and foam.
