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

SPARTER Backpack Cooler is a lightweight, insulated carry solution that keeps up to 33 cans cold for extended outings while staying water-resistant and easy to wear.

Designed for beach days, picnics, hikes or everyday errands, this cooler backpack combines thick foam insulation and a silver PEVA thermal lining to maintain low temperatures for long stretches. The pack balances cooling performance with practical organization: two insulated compartments for cold items, plus exterior pockets for personal gear and a built-in bottle opener for instant convenience. Durable, scratch-resistant nylon with a waterproof PU coating helps the bag shrug off damp conditions and light spray.

How long will the SPARTER cooler keep drinks cold?

The SPARTER uses an 8 mm thick insulation core paired with a silver PEVA thermal seal to slow heat transfer and preserve chill. Under typical conditions, beverages stay cold for many hours, making it suitable for day trips and multi-hour outdoor activities.

• 8 mm thickened foam insulation for stronger thermal resistance
• Silver PEVA inner lining improves reflective cooling performance
• Up to about 20 hours of retention under moderate ambient temperatures
• Best results when pre-chilled contents and ice packs are used

Is the bag leakproof and how should I care for spills?

The interior liner is produced with a seamless hot-press process to make the main compartment leak-resistant against melted ice and condensation. Note that the top zipper itself is not fully waterproof; avoid tipping the pack to minimize leakage and wipe the liner clean after use.

• Seamless hot-pressed liner reduces seepage from melted ice
• Top zipper is water-resistant but not fully leakproof—keep upright
• Wipe interior with a damp cloth and mild soap for routine cleaning
• Air dry open after cleaning to prevent odors or mildew

How much can it carry and how is the storage organized?

The SPARTER backpack cooler fits up to 33 standard 330 ml cans (measurements: 17" H x 10.5" L x 7.5" W). It separates cold and dry items across two insulated compartments and provides external pockets for smaller necessities.

• Main insulated compartment sized for cans, bottles, and ice packs
• Second insulated section ideal for sandwiches or chilled snacks
• Front large pocket plus two side pockets for phone, keys, napkins, or utensils
• Includes a compact bottle opener attached for on-the-go use

Is the backpack comfortable to carry and durable for outdoor use?

Constructed from high-density, scratch-resistant nylon with a waterproof PU coating, the cooler is built to withstand outdoor wear while staying relatively lightweight. Padded shoulder straps and a cushioned back panel improve comfort compared with rigid, heavy coolers.

• High-density nylon with PU coating resists scratches and dampness
• Padded shoulder straps and back panel for extended carry comfort
• Lightweight design eases transport on hikes, beaches or commuting
• Sturdy construction suited to frequent outdoor use

Who is this for? The SPARTER Backpack Cooler is aimed at active people who want portable cooling without the bulk of a hard cooler: beachgoers, day hikers, festival attendees, tailgaters and parents packing lunches. It also suits commuters and workers who need reliable temperature control for beverages and meals while carrying personal items in the same pack. If you want a balance of insulation, organization and carry comfort for day-long outings, this backpack cooler delivers practical features in a weather-resistant package.
