Design and Details

• Non-wicking Hypalon roll-top closure with patented field repair buckle
• Valve-free air permeable eVent fabric base allows soft items to be compressed
• Double-stitched and fully-taped waterproof seams
• Bluesign Approved recycled 70D nylon sidewall fabric uses a Non-PFC DWR finish
• 70D eVent face fabric is Non-PFC
• New base lash loop feature compatible with optional shoulder Sling Strap attachment
• Oval shape stacks and packs easily
• Lightweight high density weave waterproof fabric
• 70 Denier 210T nylon with a white interior polyurethane (PU) coating
• High density 210T weave gives the fabric a stronger tear strength and greater durability
• White PU coating reflects light and makes it easier to identify contents inside your dry sack
• PU coating to make two different versions of this fabric: 2,000mm (Nylon stuff Sacks, Pack covers and compression sacks) and 10,000mm (Lightweight dry sacks, eVac Dry sacks and dry compression sacks) waterhead rated
• eVent is a proprietary waterproof breathable membrane fabric with micro-fine pores that allow the passage of water vapour but not liquid
• Traditionally, waterproof and breathable PTFE (polytetrafluoroethylene) membranes glog easily by body oils, which renders them useless after a little use
• Solution was to add a PU backing to protect the PTFE membrane
• When thin enough, PU still allows vapour transmission but at a much lower rate
• Some manufacturers avoid the membrane and just use a PU coating
• PU has to be relatively thick to ensure sufficient waterproofing, resulting in even lower breathability
• Genius of eVent was to make the membrane oleophobic (oil repellent), meaning it wouldn't clog with oils, therefore didn't need the inhibiting PU layer
• Sufficiently breathable that a pressure gradient can force air through it
• eVent in this way as a purge valve in the bottom of our eVac Dry Sacks, and our Ultra-Sil and 70D Dry Compression Sacks
