Thank you for looking. This is a DCF DRY COMP BAG, size S. It was purchased new but has not been used and has been stored in a home warehouse. Thank you for your consideration. DCF DRY COMP BAG ・Size S (approx. 6L, 34g) ・Height 45cm, Width 10.5cm, Depth 12.5cm It exists, but it's rare. DCF compression. Why didn't the legendary UL brands make these? There are simple waterproof bags made of DCF. But I couldn't find anything that could be compressed tightly. If it doesn't exist, we make it. It's always like that. A message from BACKSIDE SUMMIT DESIGN "I want to compress with DCF." BSD, who enjoys playing in the good spots of the mountains relying on maps, not just peak hunting. They travel light but don't forget their campfire spirit. We share many commonalities in our outdoor inclinations. BSD sent a message saying, "I want to compress with DCF," along with a design sketch. I see, compression with DCF. "I want this too," I replied immediately, and the project began. "I want to make it compact" along with lightness. The passion of packing enthusiasts. According to BSD, "Sleeping bags and quilts, with their original bags, take up a whole backpack on their own." Exactly. Packing enthusiasts seek not only lightness but also compactness. The standard compression bags that sandwich from the top and bottom are cumbersome to use. The roll-top only type will unroll over time and lose compression. We have created something that is not only light but also simple to use and can be compressed tightly. As expected of DCF. Lightweight x Waterproof x Compressible. The weight is about half that of competing products. DCF is a fabric that does not allow water or air to pass through. High waterproofness is achieved by sealing all seams with DCF tape. The weight is about half that of competing products. This is attractive even for those who are not extreme UL enthusiasts.
