Sealline® Blocker™ Dry Sack

Cascade Designs

We offer the SeallIne Blocker Dry Sacks in 10L size as the perfect complement to your Zenbivy Bed.
  • Fully welded: Unlike most dry sacks which are sewn and taped and vulnerable to leakage, Blocker Dry sacks are welded and will remain watertight thought their life.
  • Waterproof closure: Roll-top closure features a wrinkle-free stiffening strip to ensure a secure seal when closing the dry sack.
  • Durable construction: Fully welded seams result in stronger and more durably protective construction compared to sewn-and-taped seams.
  • Efficient-Packing: PackTight packing system sacks feature flat-sided, rectangular shapes that nestle closely together, packing 20% more efficiently than rounded sacks for easy, space-saving organization.

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.
