Dry Sack
The Zenbivy Dry Sacks are designed with fully welded seams for ultimate durability and waterproof performance. Featuring a high-speed valve for compression and a lightweight yet robust construction, they ensure your gear stays completely dry while minimizing storage volume. Unlike traditional dry sacks, ours aren’t made from a single piece of fabric. The distributed compression reduces stress on the seams, resulting in a highly reliable, waterproof storage solution.
With the optional Compression Cap, you can further compress the Dry Sack, saving valuable space in your backpack.
Note: The Dry Sack is sold separately. Compression Caps are available for purchase separately.
Which size Dry Sack is right for your sleep system? Choose between 4 L, 7 L, 10 L, 15 L or 20 L and match it with the recommended Dry Sack size for your Zenbivy setup below.
With the recommended size, there’s still room for your Zenbivy Pillow and even a down jacket. Your bed will compress to about half the size of the recommended Dry Sack (e.g., a 7 L sack compresses to 3–4 L, a 10 L sack to 5 L, and so on).

Features
Features
Fully Welded Seams — Sewn and taped seams leak and the taping degrades over time. Zenbivy Dry Sacks are fully welded for 100% dry seams that will remain watertight throughout their life.
Modular Compression — Sewn compression sacks pull on seams and compromise the dry sack's waterproof integrity. We’ve made ours compression compatible. Separate compression will never stress seams, resulting in a more reliably waterproof dry sack. Compression Caps sold separately.
High-Speed Mechanical Valve — Waterproof breathable panels not only leak, but they are SLOW. Our high-speed mechanical valve instantly dumps air while remaining watertight for quick compression you can trust.
Lightweight and Durable — Other dry sacks on the market are either light OR durable. Zenbivy Dry Sacks are both. We’ve combined 30 d ripstop nylon with a burlier 75 d base to give strength where it's needed.
