【Product Details】 Color: Gray Capacity: 30L Weight: 990g 【365-Day Usable Large Capacity Cooler Bag】 Suitable for various occasions such as outdoor activities, sports, shopping, and travel. With a 30L capacity and a lightweight design of only 990g, it's easy to carry. It features a 3-way design with a shoulder strap, allowing for hand-carrying or shoulder-carrying. It can be folded compactly with the belt, so it doesn't take up space when not in use. The stylish design makes it suitable for everyday use and outdoor activities. 【5-Layer Structure x Waterproof Design】 Achieves professional-grade cooling performance and durability. The outer layer uses 600D Oxford waterproof fabric, and it's meticulously layered with PP board, EPE, non-woven fabric, and PEVA. The 5-layer structure thoroughly blocks the effects of the outside air, and the ice melts 1.5 times slower than commercially available products. The surface is abrasion-resistant, and the interior is environmentally friendly and antibacterial. Furthermore, the special hot-press technology achieves a zero-seam design, proving complete waterproofness even in a 24-hour water immersion test. It can maintain low temperatures for a long time with ice packs inside, making it ideal for storing fresh food during fishing and camping. 【5mm Plastic Bottom Plate Included】 Regular soft cooler bags often have the problem of sagging due to the weight of the luggage because they don't have a bottom plate. The West soft cooler bag solves this problem by including a dedicated antibacterial bottom plate. 【Blocks Cold Air】 There is an opening at the top (quick-serve opening) that allows you to quickly and easily take out items inside the cooler without letting the cold air escape. In addition, the main W zipper is designed with an insulation foam cover to prevent cold air from escaping. A carabiner loop is installed, allowing you to hang items such as Sierra cups and small flashlights that are often used in camping. Leave a full day's worth of food for a family of four to this West cooler box. 【Portability】 It has a handle that can be held with one hand and a shoulder strap for easy carrying. It can be folded compactly when not in use, so it doesn't take up storage space. $$2580 Cooler Box Insulated Bag [Recommended by Outdoor Guides] 30L Large Capacity Cooling Insulation 5-Layer Insulation Structure Foldable Compact Cooler Bag Camping Sports Outdoor
