Product Description

First, the Cooler Bag Backpack for Picnic is a hands-free insulated bag for outdoor lovers. It keeps food and drinks fresh for full-day picnics and park trips. It uses a 4-layer structure for reliable temperature retention. Its water-repellent polyester outer layer blocks splashes and light rain. The high-density EPE foam middle layer delivers strong thermal insulation. An aluminum foil layer locks in cold or heat more effectively. The seamless food-grade PEVA lining is 100% leak-proof and safe for food.
Second, this picnic cooler backpack offers 30L of extra-large storage space. It holds up to 48 standard 355ml cans for group outings. You can easily pack meals, fruits, ice packs and snacks for multiple people. It also comes with multiple practical pockets for daily use. The front zipper pocket stores utensils and small accessories. Side elastic mesh pockets fit water bottles or foldable umbrellas. The wide top opening lets you grab large food containers in seconds.
Furthermore, this cooler backpack beats traditional hand-held cooler bags on portability. It has ergonomic padded breathable shoulder straps for all-day comfort. The straps evenly distribute weight to reduce shoulder strain during long walks. The hands-free design leaves room for picnic mats and other gear. It works perfectly for hiking, camping, fishing and food delivery too. We also offer full OEM customization services for bulk wholesale orders.
