Sealline® Blocker Compression Dry Sack

Cascade Designs

If you just must have a traditional compression dry sack, this is the one to get.

We find that regular dry sacks compress and pack more easily (See Blocker Dry Sack), but some people don't want to compress and pack at the same time and are not concerned about the extra complexity and weight.

Sealline addressed the two key weaknesses in most compression dry sacks:

1.  Most compression dry sacks are sewn and taped, and use a waterproof-breathable panel to expel air.  Blockers are fully welded and use a mechanical valve, so they are MUCH more reliably watertight.

2.  Most compression sacks stress critical seams when compressing.  The Blocker compression system is independent of critical seams, so it is much more durable and MUCH more reliably watertight.

Size Guide

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.
