The Sea to Summit Lightweight Stuff Sack is ideal for organized modular packing of gear and clothing for backpacking, camping, hiking, and travel. Manufactured from bluesign-approved 70D PU-coated nylon, with a PFC-free DWR finish; 2,000mm waterhead (the higher the waterhead rating, the more waterproof the fabric). A tear-proof drawcord closure with durable Hypalon pull tabs provides quick and easy access to bag contents and a light-reflecting white interior coating makes it easy to see what’s inside. The Sea to Summit Lightweight Stuff Sack has a round base with a webbing pull handle for easy carry. Seams are double stitched, and reinforced at stress points for added strength and durability. Available in six sizes: 3 liter, 5 liter, 8 liter, 13 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.)
