This is a roll-top stuff sack made from DCF Dyneema (Cuben Fiber) 1.0oz in gray. It is excellent in waterproofness and strength, and is a lightweight material suitable for outdoor use. Also, it is quite thin and the contents are visible. It is convenient for sorting bags or hanging on a backpack for easy access. This item is not completely waterproof as the seams are not waterproofed. You may see unevenness in the fabric fibers, and fine wrinkles may appear during production or use, but it will soften and become more familiar overall with each use. Size: Approximately 39.5cm (height) x 22cm (width) Weight: Approximately 18g Wrinkles from import or production, and creases from mailing may be present. Also, although we make them as carefully as possible, please understand that these are handmade products before purchasing. *Items other than the stuff sack in the photos are not included. *If you purchase multiple items, the shipping cost may be reduced, so please let us know in the comments before purchasing. #X-pac #UL material #Mountaineering #Dyneema #Outdoor #Pouch #Stuff bag #Roll-top bag #Lightweight bag #DCF Material: DCF
