How To Choose a Dry Sack

read the full blog post here

Fully Welded

Unlike most dry sacks which are sewn-and-taped and therefore vulnerable to leakage, Zenbivy Dry Sacks are fully welded and will remain watertight throughout their life. 

Instant Compression

The patent pending Duck Air Dump Valve may sound like a duck, but our one-way valve design dumps air faster than any other! That means quick, easy compression with a reliable water seal you can trust.

Lightweight & Durable

Why pair lightweight gear with a heavy dry sack? We've built one of the lightest on the market, with no sacrifice to durability. Made from featherweight 30D rip stop nylon, it blocks water while barely tipping the scales. The base is a burlier 75D nylon to give strength where it's needed. Even the large 15L Dry Sack weighs in under 3 ounces!

Compression Compatible

Unlike all-in-one compression sacks, we made our Zenbivy Compression Caps an optional separate component. For those longer trips where you need to maximize the space in your pack, simply add on the Caps and tighten the straps to instantly shrink it down.

You can expect your Bed to compress down to roughly half the size of its recommended Dry Sack.


Dry Sack Specifications & Fit

Size Chart

Unlike mummy bags, there is no thermal disadvantage to a larger size Zenbivy Bed because it is always free to wrap snugly around you. So bigger is always more comfortable and just as warm. If you are an "active" sleeper or have a "wide" sleeping position, you may want to size up to sleep naturally. When in doubt, size up.
