SPARTER Large Backpack Cooler 49-Can — Waterproof Insulated Cooler, 20-Hour Cold Retention

Designed for beach days, camping trips, tailgates and outdoor work, this cooler backpack pairs thick 8 mm foam insulation with a silver PEVA liner to extend cold retention. The high-density nylon shell with a waterproof PU coating resists splashes and surface wear, while chest and waist buckles distribute load for longer comfort. Multiple pockets and a dedicated dry compartment let you organize food, beverages and personal items without sacrificing cooling performance.

How long will this cooler keep my drinks cold?

With a reinforced 8 mm foam core and a reflective silver PEVA interior, the SPARTER backpack cooler is engineered for extended cold retention. In typical outdoor use you can expect cooling performance up to about 20 hours, depending on ice quality, ambient temperature and how often the bag is opened.

• Thickened 8 mm foam insulation for extended thermal barrier
• Advanced silver PEVA seal to reflect heat and lock cold in
• Best results when pre-chilled and kept closed as much as possible

Is the backpack leakproof and how should it be handled?

The interior liner uses a high-tech seamless hot-press process to resist leaks, so pooled water from melting ice is contained inside the main compartment. Note that the exterior zipper is not fully leakproof; avoid tipping the pack on its side or upside down to prevent spills.

• Seamless hot-pressed liner for reliable containment
• Zipper is water-resistant but not impermeable—keep upright
• Easy-to-clean inner lining for quick draining and drying

How much can I fit and how is the bag organized?

This model fits up to 49 standard 330 ml cans and measures 17.5" H x 11.75" L x 8" W, leaving room for tall cans, bottles, meals and snacks. Two insulated compartments separate chilled items from dry goods, while exterior pockets keep phones, keys and utensils accessible.

• Main insulated compartment holds up to 49 cans (330 ml)
• Second insulated section for dry or additional cold items
• Front zip pocket and two side pockets for accessories and bottles
• Includes a bottle opener for on-the-go convenience

Will it be comfortable to carry over long distances?

Yes — the SPARTER cooler backpack uses padded shoulder straps plus chest and waist buckles to spread weight and reduce shoulder strain. The breathable back panel and ergonomic strap layout help keep you comfortable during hikes, walks on the sand or while carrying heavier loads.

• Padded shoulder straps with adjustable chest and waist buckles
• High-density nylon with PU coating for durability and lightness
• Balanced design for stable carrying on uneven terrain
