ALPS Mountaineering Dry Sack 35L - Waterproof Air-Control Compression (Blue/Gray)

Overview

The ALPS Mountaineering Dry Sack 35L in blue and gray combines a practical compression design with Air Control technology. This means you can squeeze out air during packing while the bottom fabric remains waterproof, helping you save space without compromising protection. It is not designed for full submersion, but it excels in damp, rainy, or river-crossing environments where keeping gear dry matters.

Built to endure backcountry use, the Dry Sack features reinforced 70D nylon ripstop side panels and a durable waterproof coating. Bartacked stress points and heavy-duty nylon webbing bolster its strength, so the sack stands up to rugged terrain, thorny trails, and repeated loading in challenging conditions. All seams are taped and sealed, providing a reliable moisture barrier for clothing, sleeping gear, or electronics against rain, splashes, or ground moisture.

Handling is straightforward thanks to a bottom grab handle and multiple compression straps. These touches make it easy to cinch down the load and quickly retrieve or reposition packed gear. The series offers a range of capacities—10L, 20L, 35L, and 45L—so you can tailor packing to your setup, whether you’re organizing a compact clothing kit or a layered sleep system. Clear labeling helps with fast gear sorting and integration into your pack system.
