The Sea to Summit Ultra-Sil Compression Sack squishes down bulky clothing and gear to maximize packing space when backpacking, camping, or traveling. Manufactured from lightweight 30D Ultra-Sil Cordura nylon, its slippery finish makes it easy to slide bags into tight spaces for better packing. A flip-top lid with a drawcord closure provides quick and easy access to bag contents. Four extra-long straps allow for max capacity and even compression. The Sea to Summit Ultra-Sil Compression Sack has a round base with a reinforced webbing pull handle for easy carry. Seams are double stitched, and stress points are bartacked for durability. Available in five sizes: 6 liter, 10 liter, 14 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.)
