I have experimented with all kinds of stuff sacks, trying out different brands, materials, sizes, and styles. A favorite has finally emerged! I've used Yama Mountain Gear Cuben Fiber stuff sacks for backcountry hikes, everyday use around town, and work travel for several months now and am so pleased to offer them here. These stuff sacks are whisper light, tough as nails, and designed and made with care by thruhikers Gen Shimizu and Greg Arpante in Charlottesville, Virginia. The Cuben Fiber is translucent, so you can see what's inside when you are searching for your stuff in your backpack, purse, or suitcase. The flat style is like an envelope with a slick Spectra drawcord at the top and a mini barrel cord lock that's small enough to keep the weight super low but large enough to grip easily when your hands are cold or covered in sunscreen. This size is great as a catch all sack for small items, and the water resistant Cuben Fiber will keep them all dry. 

FYI: Made from crazy durable Dyneema Cuben Fiber, this flat stuff sack measures 6x8 inches and measures up at a barely-there .10 ounces (3 grams). For more sizes and shapes, check out the Yama Mountain Gear Cuben Fiber Cylindrical Sacks.
