Evac Compression Dry Bag UL

eVent fabric is an air-permeable, waterproof laminate used in two different functional areas in Sea to Summit products:

• In the base of our best-selling eVent Compression Dry Sacks, Evac Dry Sacks and Ultra-Sil Compression Dry Sacks. In this application, the laminate utilizes a 40 denier nylon face fabric: the material allows air to be pushed out of the dry sack/compression dry sack but prevents water from entering. This means you can compress the air out of a dry sack without needing a purge valve! In the upper section of our Quagmire and Alpine Gaiters. In this application, the laminate utilizes a 70 denier nylon face fabric. The material allows perspiration to pass through easily but prevents external water from entering. The result: waterproof protection and superior breathability!

Sea to Summit sleeping bags do not contain PFCs.

Ultra-Dry Down™  uses a non-PFC hydrophobic treatment to ensure it absorbs less moisture and dries more quickly. The treatment does not affect the breathability or the lifespan of the down and lasts through at least 20 washings.

The down used in our sleeping bags is RDS-certified responsibly sourced.

Down and synthetic-insulated sleeping bags utilize a non-PFC DWR treatment on the shell fabric for external moisture repellency. This helps prevent the insulation from becoming damp if the sleeping bag comes into contact with condensation on a tent wall, for instance. 

An incredibly lightweight yet durable fabric used in a large number of Sea to Summit products. This 30 denier Nylon is made with CORDURA yarns for strength, woven into a ripstop pattern. Two versions of the fabric are used:

• Water-resistant products (such as the Ultra-Sil Stuff Sacks) are siliconized on both sides for ultimate packability
• Waterproof products (such as the UltraSil Dry Sack are) siliconized on the outside and PU-coated on the inside to allow seam taping.
• Both versions have a hydrostatic head greater than 2000mm – which makes them more than adequately waterproof for the types of environments they are intended for.
