Sea to Summit Ultra-Sil Compression Sack

Sea to Summit Ultra-Sil Compression Sack

The Sea to Summit Ultra-Sil Compression Sack shrinks a sleeping bag, puffy or stack of clothes by as much as two thirds. This 8 liter compression stuff sack uses ultralight silnylon and three compression straps to free up real space in your pack.

Why We Carry It

It is the compression sack we hand people who are trying to make a bulky bag fit, and the weight is low enough that ultralight folks don't argue with it.

Highlights

• Ultra-Sil 30D nylon: bluesign approved nylon that is light and tougher than it looks.
• Water resistant: Non-PFC DWR finish and a 2000 mm hydrostatic head shed moisture.
• Big compression: Crush soft contents down by up to two thirds.
• Three straps: Two ladderlock straps and one side release buckle for even compression.
• Barely there weight: Just 64 g / 2.3 oz, so it earns its spot in a light kit.

Best For

Summer quilts, puffies and clothes for fast overnights out of the Methodist Mountain trails, or squeezing a travel wardrobe into a small bag.
