Sea to Summit Ultra-SIL Compression Sack for Ultralight Outdoor and Travel Storage

The Sea to Summit Ultra-Sil Compression Sack squishes down bulky clothing and gear to one-third the size to maximize packing space when backpacking, camping, or traveling. Manufactured from bluesign-approved 30D Ultra-Sil Cordura nylon, its slippery finish makes it easy to slide bags into tight spaces for better packing. An attached flip-top lid prevents tangled straps, and hides a drawcord closure for quick and easy access to bag contents. Three straps allow for max capacity and even compression, and feature two ladderlock and one side release buckle. 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 reinforced at stress points for added strength and durability. Available in five sizes: 5 liter, 8 liter, 13 liter, 20 liter, and 35 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.)
