※ After purchase, please inform us of your desired color (Black or Gray) via the transaction message. 【Product Description】 A roll-top pack liner that maximizes the waterproof properties of DCF (Dyneema). It ensures waterproof protection for items you absolutely don't want to get wet, such as sleeping bags and changes of clothes. Only the roll-top opening is sewn with a sewing machine, and the body is finished with bonding pressure only, so the waterproof performance is considered to be higher than seam sealing with a sewing machine. ※ DCF has the weakness that the needle holes of the sewing machine expand due to pressure, so Under Dog Gear minimizes sewing machine sewing. Other features below: ・Made with thick 1.43oz DCF (Dyneema) for tough use. ・Suitable size for packs of 35L or more. (Example 1: For 3 seasons, ~800g down sleeping bag, insulation, long pants, socks, etc.) (Example 2: For winter, down sleeping bag, a small amount of change of clothes, etc.) ・The bottom is finished in a rectangular shape to match the shape of the pack, so it does not impair the fit when carrying the pack. 【Specs】 Material: DCF (Dyneema Composite Fabric) 1.43oz Color: Black, Gray Size: Height 56 x Width 39 x Bottom (24 x 14) cm Capacity: Approximately 19L Recommended pack size: 35L or more Weight: 48g ※ There may be slight changes in parts such as threads from the photos. ※ Due to the nature of the fabric, some wrinkles may occur during the manufacturing process.
