SPARTER Insulated Backpack Cooler 33-Can Capacity — Leakproof PEVA Liner, Water-Resistant Nylon

The SPARTER Backpack Cooler is an insulated, lightweight cooler bag that carries up to 33 cans while protecting contents with a leakproof inner liner and water-resistant exterior.

Built for days at the shore, short hikes, tailgates or work sites, this backpack-style cooler balances temperature retention with portability. Thick 8 mm foam insulation combined with a silver PEVA interior keeps drinks chilled for extended periods, while the nylon shell and PU coating resist splashes and abrasion. Two insulated compartments plus multiple exterior pockets keep cold items separate from dry goods and accessories.

How long will the SPARTER cooler keep drinks cold?

With its thickened 8 mm foam core and reflective PEVA lining, this backpack cooler can maintain low temperatures for prolonged outings. Actual performance depends on starting temperature, amount of ice, exposure to sun, and ambient heat, but the design targets up to 20 hours of cold retention under typical use.

• 8 mm foam insulation for thermal resistance
• Silver PEVA reflective inner seal to reduce heat transfer
• Best results when precooled and kept out of direct sun

Is the interior leakproof and easy to clean?

The cooler uses a high-tech seamless hot-pressed liner that resists leaks along seams, so melted ice and spills stay inside the main compartment. Note that the zipper itself is not fully waterproof, so you should avoid tipping the pack on its side when it contains liquid.

• Seamless hot-press inner liner prevents seam leaks
• Wipe-clean PEVA surface for quick maintenance
• Zip closure should be kept upright to avoid spills

What organization and carrying features does it offer?

This model provides two insulated compartments to separate cold drinks from dry snacks or gear. Exterior pockets hold small essentials, and padded straps plus a cushioned back panel make the bag comfortable to wear for extended periods.

• Two insulated compartments for chilled and dry items
• Large front pocket and two side pockets for phones, wallets, or accessories
• Padded shoulder straps and back panel for carrying comfort
• Includes built-in bottle opener for convenience

How big is the backpack and what fits inside?

The SPARTER cooler measures 17" H x 10.5" L x 7.5" W and fits up to 33 standard 330 ml cans. The shape also accommodates taller beverages, packaged meals, snacks, and small personal items, making it versatile for day trips and social events.

Who is this for?

Its lightweight nylon shell and padded carrying system make it a good pick for active days when comfort and temperature control matter.
