This is the Ultra-Sil Nano Daypack from SEA TO SUMMIT. I purchased it two years ago but am selling it because I haven't had the opportunity to use it. Made from ultra-lightweight 15D nylon fabric, it weighs only 30g but has a load capacity of 20kg. It's a small but strong and reliable daypack. When not in use, it folds down to an egg-sized compact that can be attached to a pocket or keychain, so you can always carry it with you.
