Sea to Summit Waterproof Ultra-Sil Compression Dry Sack

It was the success of Sea to Summit's Compression Dry Sacks that prompted the creation of a lightweight version.

It boasts the same clever functionality as the original Compression Dry Sack - by using air permeable eVent fabric that allows air to be pushed out of the sack, without allowing water in. It's now ultra-light - compressing gear to one-third of it's volume while keeping it dry.

• Air passes out through eVent fabric for efficient compression.
• Made from Ultra-Sil 30D siliconised high-tenacity Cordura tylon fabric with exceptional strength.
• Waterproof seams, double stitched and fully tape sealed.
• Waterproof and air-permeable eVent fabric base.
• Hypalon closure does not wick moisture.
• Reinforced stitching on all stress points.
• Air compresses out, water can't get in.
• Roughly half the weight of the original Compression Dry Sack.
