backpack insulated cooler

Capacities vary by model. Common can capacities include about 14, 18, 20, 24, 33 and 35 cans. Equivalent volume listings include roughly 14.8 quarts, 18 quarts and 27.87 quarts—so expect models from small lunch-size bags up to larger 20–35 can packs.

Most listings use PEVA liners (often heat-sealed) and polyester or Oxford-style exterior fabrics. Insulation commonly includes foam layers—some specify thicker foam such as 8 mm—and multi-layer constructions (for example foam paired with a reflective/silver PEVA layer).

Exterior fabrics commonly include polyester, recycled polyester or Oxford cloth. Many models feature water-resistant treatments such as PU coatings or waterproof/scratch-resistant finishes to help repel moisture and make the bag easier to clean.

Sizes range from compact models (for example about 9 x 7.5 x 11.5 inches or 12 x 6 x 8.5 inches) up to larger backpacks (around 17.5 x 11.75 x 8 inches). Listed weights typically fall between roughly 1 and 2.2 pounds, depending on size and materials.

Care is usually simple: spot-clean the exterior and wipe the liner with a damp cloth. Most listings recommend wiping or hand-cleaning rather than machine washing; a few note that exterior areas can be rinsed with water if needed.
