Cold Drinks, Hands Free, On Your Brand
Thick closed-cell foam insulation keeps contents cold for extended periods. Cabinet and schedule independent, this backpack format leaves your hands free for other gear. Thicker foam directly improves thermal resistance, which is why this backpack uses solid insulated walls rather than a thin single-layer lining.
Waterproof Exterior, Leak-Proof Interior
The tear-resistant exterior sheds rain, and the welded-seam liner keeps meltwater inside, so the pack is reliable at the beach, on a trail or in a car. Padded straps and back panel keep it comfortable for a full day of carry.

Frequently Asked Questions
How long does the cooler backpack keep drinks cold?
Thick closed-cell foam insulation keeps drinks cold for many hours in typical conditions, and pre-chilling the bag or adding frozen gel packs extends the cold window. (Source: U.S. Department of Energy insulation guidance)
What capacity does the cooler backpack have?
It carries a large volume of bottles and cans with room for ice, designed for hiking, beach days, tailgating and promotional programmes. (Source: JUNYUAN Bags OEM/ODM)
Is the cooler backpack leak-proof and waterproof?
Yes. The welded seams and leak-proof liner keep meltwater inside and the exterior sheds rain, so it is designed for leak-proof carry rather than total submersion. (Source: JUNYUAN Bags OEM/ODM)
What branding options are available for wholesale?
Screen printing, heat transfer for full-colour logos, embroidery on straps, rubber patches and custom woven labels, plus Pantone colour matching, hangtags and retail packaging. (Source: JUNYUAN Bags OEM/ODM)
Can you supply eco-friendly or recycled fabric versions?
Yes. A recycled-fabric (RPET) exterior upgrade is available for sustainability-focused brands, with material documentation supplied on request. (Source: JUNYUAN Bags OEM/ODM)

Custom samples ship in 6-10 days after artwork approval and bulk production runs 35-50 days, with AQL 2.5 quality control and a 12-month warranty. (Source: JUNYUAN Bags OEM/ODM)
What is the MOQ for custom logo cooler backpacks?
The standard MOQ is 500 pieces per design, with flexible programmes available for new brands through our sales team. (Source: JUNYUAN Bags OEM/ODM)
How do I clean the cooler backpack?
Wipe the leak-proof lining with a damp cloth and mild soap, rinse and dry fully, and wipe the exterior to remove sand and dust after outdoor use. (Source: JUNYUAN Bags OEM/ODM)
