This bag can be used for bikepacking. I'm not sure about the material. It's clear and lightweight, but it doesn't seem to be DCF. I think the construction is excellent, with features like magnetic closures, a pocket for displaying stickers, race numbers, etc., and zippers. It's useful for bike trips, as well as regular travel, hiking, and camping. It also has an ultralight (UL) feel. I'm selling it to organize my gear. The following description is quoted from the shop's description: "When you wish you had just a little more..." It can be a bag or a pouch. It can be mounted on a vehicle, and in a camp setting, you can hang it on a tree or attach it to a pole... The uses are endless. Magnets are incorporated into the opening and closing mechanism, making it easy to open and close, and preventing items from falling out. Liters: ~4.2L
