The Sea to Summit Ultra-Sil Stuff Sack is an ultra-lightweight option for organizing gear and clothing in a backpack or bag, for any outdoor or travel adventure. Manufactured from bluesign-approved 30D Ultra-Sil Cordura nylon, its slippery finish makes it easy to slide into tight spaces for better packing. A tear-proof drawcord top opening with a durable Hypalon pull tabs provides quick and easy access to bag contents. The Sea to Summit Ultra-Sil Stuff Sack has a round base with a reinforced webbing pull handle for easy carry. Seams are double stitched and reinforced at stress points for added strength and durability. Available in two size configurations: 3L, 5L, 8L and 5L, 8L, 13L , 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.)
