The Sea to Summit Nylon Stuff Sack is ideal for organized modular packing of gear and clothing for backpacking, camping, hiking, and travel. Manufactured from tough, water-resistant 70D PU-coated nylon, it features a white interior coating that sheds moisture, and makes it easy to find what's inside. A tear-proof drawcord closure provides quick and easy access. The Sea to Summit Nylon Stuff Sack has a round base with a webbing pull handle for easy carry. Stress points are bartacked, and edges overlocked for durability. Available in seven sizes: 2.5 liter, 4 liter, 6.5 liter, 9 liter, 15 liter, 20 liter, and 30 liter, to carry everything from small essentials to group gear. Sea to Summit products are guaranteed against defects in materials or workmanship for the lifetime of the product. (Note that stuff sacks do not have taped seams or a roll-top closure; they are water-resistant, not waterproof.)
