Our Travel Stuff Sacks serve a variety of purposes: they stow and compress items like down/polyfill jackets and vests (constraining them to a smaller amount of space), they can be used to separate dirty clothes from clean clothes, and some folks prefer to use them for packing clothing that doesn't need to be folded (like underwear — we don't fold our underwear — do you? On second thought, let's not go there).
The shape of our Travel Stuff Sacks is a little different than what you might expect: the bottom isn't square nor is it round. Rather, it's an elongated or flattened circle, or oval -- this shape is pleasing to the eye and helps make the Travel Stuff Sacks pack efficiently in bags like the Aeronaut and Synapse.
Travel Stuff Sacks are available in four sizes: 1 (very small - very light down vest), 2 (small - very light down jacket), 3 (medium - down jacket), and 4 (large - all of the above). Each size is available in a variety of colors -- great for those of you who like to organize/pack by color ("I keep socks in the Wasabi Travel Stuff Sack and underwear in the Steel Travel Stuff Sack").
Travel Stuff Sacks are made from our 200 denier Dyneema/nylon ultralight rip-stop fabric produced especially for us in Japan and dyed in our own custom colors; they cinch shut with a drawstring closure and cord lock.
