※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 waterproofness of DCF (Dyneema). It ensures waterproofness, allowing you to safely pack items you absolutely don't want to get wet, such as sleeping bags and changes of clothes. Only the roll-top portion of the opening is sewn with a sewing machine, and the body is finished only with bonding pressure, so we believe the waterproofness is 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 25-30L packs (Example 1: In summer, ~500g down sleeping bag, upper and lower changes of clothes, etc.) (Example 2: In winter, ~1000g down sleeping bag) ・The bottom is rectangular to match the shape of the pack, so it doesn't compromise the fit when you wear the pack. 【Specs】 Material: DCF (Dyneema Composite Fabric) 1.43oz Color: Black, Gray Size: Height 49 x Width 33 x Bottom (22 x 11) cm Capacity: Approximately 12L Recommended pack size: 25-30L Weight: 34g ※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.
