Hyperlite Mountain Gear’s ultralight stuff sacks are very strong, nearly weightless, made of 100% waterproof Cuben Fiber and are essential for protecting against rain and moisture. HMG's stuff sacks come in either round roll-top versions or flat draw-string versions ranging in size from nano to jumbo intended to suit any of your lightweight outdoor adventure needs. CF8 Stuff Sacks are transparent and great for compartmentalizing your gear in a way that allows you to see what is inside each sack while keeping your gear or food absolutely dry. CF11 Stuff Sacks are made from a version of Cuben fiber that is 40% stronger and a bit more durable. CF11 Stuff Sacks come only in black and are great for storing tent stakes, cooking equipment, or any of your other gear, and used with CF8 Stuff Sacks, are a great way to color code your compartmentalized gear. And we even have a handy stuff sack pillow that doubles for gear organization and a soft camp pillow. See our Special Deals for cost saving Stuff Sack Sets.
