Maelstrom Insulated Cooler Backpack 35-Can — Leakproof Padded Soft Cooler with Heat-Sealed PEVA

Maelstrom's 35-can insulated cooler backpack is a leakproof, padded soft cooler that carries lunches, drinks and picnic gear while keeping contents cold or warm for hours.

This multi-compartment cooler backpack blends a dedicated insulated compartment with organizational pockets and outdoor-ready features — ideal for beach days, hikes, road trips and packed lunches. Built with thick PEVA lining, dense foam insulation and heat-sealed seams, the bag resists drips while the ergonomic straps and chest buckle keep loads comfortable on long walks.

How much will fit and how is it organized?

The main insulated compartment holds up to 35 standard cans (about 27–32 L usable) and leaves room for ice packs, bottles or meal containers. Multiple external and internal pockets keep electronics, utensils and small essentials separate from food.

• Main insulated cavity sized for 35 cans (approx. 27 L–32 L capacity)
• Front cutlery organizer that secures utensils and plates, with two condiment bottle holders
• Top zip pocket for phone or snacks; front zip pocket for tablets and cords
• Two mesh side pockets with adjustable straps for water or wine bottles
• Hidden rear zip pocket for valuables and shoulder-strap card pocket for transit cards

Will it keep food and drinks cold or hot, and is it leakproof?

The insulated liner and thick foam core are engineered to preserve temperature, and with properly frozen packs you can expect cold retention for many hours. The interior is hot-pressed PEVA with heat-sealed seams to help prevent leaks and make cleanup quick.

• Thick foam insulation paired with PEVA hot-pressed lining
• Heat-sealed seams designed to stop dripping and contain spills
• Interior surface wipes clean easily after use
• Best results when used with freeze packs for extended cold retention (up to about 16 hours depending on conditions)

What extras make it useful for outdoor activities?

Small, practical details turn this cooler backpack into a go-anywhere kit: a built-in bottle opener, sunglass cord, webbing attachment points and a chest buckle that doubles as a whistle. The padded back and S-shaped shoulder straps are breathable, adjustable and meant to reduce fatigue on longer outings.

• Stainless-steel bottle opener attached to a shoulder strap
• Shoulder strap stretch cord for sunglasses and webbing loops for tools or keys
• Adjustable wine-bottle buckle beside a reinforced mesh pocket
• Padded breathable back panel, adjustable chest strap with survival whistle

How comfortable is it to carry all day?

The bag is designed for day trips with thicker padding on the back and cushioned S-shaped straps to distribute weight evenly. A sturdy top handle also makes short lifts easier and the chest strap keeps the pack stable during movement.

• Ergonomic padded back for airflow and comfort
• Adjustable, breathable padded shoulder straps minimize shoulder strain
• Chest strap secures load and includes a whistle for emergencies
• Durable carry handle for quick grabs and transport
