Dyneema Composite Fabric is incredibly light, strong, and waterproof. However, when sewn with a regular sewing machine, the needle holes become weak points. Despite being a waterproof material, water can enter through the seams. That defeats the purpose. This dry bag is finished with bonded pressure bonding. The fabric is joined together using heat and adhesive, minimizing the need for sewing. This allows the airtightness and waterproofness of the DCF to be maintained. The structure complements the material's performance. By rolling up the roll-top opening, the contents stay dry even in sudden rain. Weight: 19g. It's hard to believe it has a 4L capacity at this weight. The M size is suitable for two t-shirts, one pair of long pants, a hand towel, and underwear. It's also perfect for storing a down jacket during a multi-day backpacking trip. Put anything you absolutely don't want to get wet in here. At first glance, it's a regular dry bag. But the construction is different. 【Specifications】 Material: DCF (Dyneema Composite Fabric) 1.43oz Colors: Black, Gray Size: Height 32 x Width 22 x Bottom (16 x 5) cm Capacity: 4L Weight: 19g ※ There may be slight changes in parts such as thread from the photos. ※ Due to the nature of the fabric, some wrinkles may occur during the manufacturing process.
