Sea To Summit EVAC 13L Dry Sack - Beluga

Sea To Summit EVAC 13L Dry Sack - Beluga: Lightweight Valve-Free Compression Dry Sack for Sleeping Bags, Insulation, and Mid-Volume Pack Organisation

The Sea to Summit EVAC 13L Dry Sack in Beluga scales the proven EVAC system up to the mid-volume format that handles the most critical compressible items in any backpacking kit — sleeping bags, down jackets, and insulated layers. The same bluesign-approved recycled 70D nylon waterproof body and eVent air-permeable waterproof base that define the EVAC range deliver valve-free compression at 13 litres without straps, purge valves, or mechanical complexity: pack your compressible items, roll the hypalon closure down, and push or sit on the sack to expel air through the eVent base while water stays completely out. For South African backpackers, kayakers, and adventure travellers who want a genuinely waterproof and compressible sleeping bag carrier or insulation organiser that adds minimal weight and integrates cleanly into any pack, the EVAC 13L in Beluga is the mid-range format that covers the most important compression job in the kit.

Key Benefits:

* eVent Air-Permeable Waterproof Base: The 70D eVent fabric base allows air to pass freely outward when the sack is squeezed or sat upon, while preventing water from entering in the opposite direction — delivering reliable valve-free compression that genuinely reduces the packed volume of a mid-range three-season down sleeping bag or large insulated jacket without any mechanical valve to fail, lose, or maintain in the field
* Valve-Free Compression Without Straps: Pack compressible items, roll the hypalon closure, and press the air out through the eVent base — the 13L volume is optimally suited to a mid-range three-season down sleeping bag or a two-season bag plus a liner, a large down jacket and insulated trousers, or a full insulation layer system for a multi-day alpine route, all without compression buckles or straps to manage
* Bluesign-Approved Recycled 70D Nylon Body: The main body is constructed from recycled and bluesign-approved 70D nylon — meeting independent certification standards for responsible material sourcing and ethical production — with a C0 non-PFC DWR finish across both the body and eVent base fabrics, maintaining full waterproof performance without PFAS chemicals throughout the bag's working life
* Hypalon Non-Wicking Roll-Top with Field Repair Buckle: The hypalon roll-top closure maintains a reliable waterproof seal without wicking moisture into the closure material itself, and is secured with Sea to Summit's patented Field Repair Buckle — replaceable in seconds with a standard Phillips screwdriver with no adhesives or tools required, extending the working life of the sack across years of hard South African backcountry use
* Oval Base with White Interior Coating: The oval base profile integrates cleanly into the contoured spaces of modern backpacks, travel bags, and kayak hatches without wasted dead space, while the white interior coating provides maximum contrast for gear visibility inside the sack in low-light conditions at dawn starts, evening camp setups, and night packing after a long day on trail
* Double-Stitched and Tape-Sealed Seams: All seams are double-stitched and fully tape-sealed for waterproof integrity across the complete sack — not limited to the closure — ensuring the 10,000mm hydrostatic head rating is maintained throughout the bag body for reliable sleeping bag protection in rain, river crossing, capsize, and wet camp conditions

At 13 litres, the EVAC sack is the ideal size for a mid-range three-season down sleeping bag — such as the Sea to Summit Spark -9°C — or a two-season synthetic bag, a large down jacket and insulated layer combination, or a full insulation layer kit for cold-weather alpine days. The Beluga grey colourway keeps a neutral, organised profile inside the pack and pairs with the full EVAC size range — 3L through 65L — for a completely modular dry organisation system where each size category handles specific gear types. Pro tip from Sea to Summit: after compressing the air out, immediately pack the EVAC sack into a tight space in your bag so the eVent base cannot draw air back in — the sack stays compressed and the volume saving is maintained for the full trip duration.
