Sea To Summit EVAC 3L Dry Sack - Beluga

Sea To Summit EVAC 3L Dry Sack - Beluga: Lightweight Valve-Free Compression Dry Sack for Compact Backpack Organisation

The Sea to Summit EVAC 3L Dry Sack in Beluga is the smarter way to waterproof and compress small essentials inside your pack — no purge valve required. The EVAC system pairs a bluesign-approved recycled 70D nylon waterproof main body with an eVent air-permeable waterproof base that lets you push air out freely while preventing any water from entering, delivering genuine compression without straps, valves, or complicated mechanics. At 3 litres, it is purpose-sized for the items that live closest to your kit — a down jacket, lightweight base layer, critical electronics protection layer, or first aid and navigation essentials — keeping them dry, compressed, and easy to locate thanks to the white interior coating. For South African backpackers, trail runners, kayakers, and travellers who want modular, waterproof organisation without adding weight or complexity to their system, the EVAC 3L in Beluga is the essential small-format dry sack.

Key Benefits:

* eVent Air-Permeable Waterproof Base: The 70D eVent fabric base is the defining technology of the EVAC system — air passes freely through the laminate when you squeeze the sack, but water cannot enter in the opposite direction, delivering valve-free compression that genuinely reduces pack volume without any mechanical components to fail, lose, or maintain
* Valve-Free Compression Without Straps: Simply pack your compressible items, roll the hypalon closure down, and press or sit on the sack to push air out through the eVent base — no straps to adjust, no purge valve to open and close, and no risk of valve failure in the field, making the EVAC one of the most reliable and user-friendly compression dry sacks Sea to Summit produces
* Bluesign-Approved Recycled 70D Nylon Body: The main body fabric is both recycled and bluesign-approved — meeting independent certification standards for responsible material sourcing and production — with a C0 non-PFC DWR finish on both the body and base fabrics for moisture shedding without PFAS chemicals, a meaningful environmental commitment across the full EVAC range
* Hypalon Non-Wicking Roll-Top with Field Repair Buckle: The hypalon roll-top closure does not wick water into the sealing material — maintaining a reliable waterproof seal across wet conditions — and is secured with Sea to Summit's patented Field Repair Buckle, replaceable in seconds with a standard Phillips screwdriver without adhesives or specialist tools for extended field life
* Oval Base with White Interior Coating: The oval base profile slides cleanly into the contoured internal spaces of modern backpacks and travel bags without the wasted dead space created by round-base sacks, while the white interior coating dramatically improves visibility when locating specific items inside the sack in low-light conditions at camp, on the trail, or in a vehicle
* Double-Stitched and Tape-Sealed Seams: All seams are double-stitched and fully tape-sealed for waterproof integrity throughout the bag — not just at the closure — ensuring that the 10,000mm hydrostatic head rating is maintained across the full sack, not just the main body fabric

At 3 litres the EVAC sack is optimally sized for a compact down jacket or insulated layer, critical dry electronics like a GPS device or satellite communicator in a secondary waterproof layer, a first aid kit, lightweight gloves and buff, or any small collection of items where reliable waterproofing and compressed packing matter simultaneously. The Beluga grey colourway keeps a neutral, clean profile inside the pack and the oval shape integrates neatly alongside other EVAC sizes for a fully modular dry organisation system. Pro tip from Sea to Summit: after pushing the air out, immediately pack the EVAC sack into a tight space in your bag so it cannot draw air back in through the base — the sack will remain compressed for the duration of the trip.
