Seal Line Blocker PurgeAir Dry Sack 20Ltr

Featuring a waterproof valve that purges trapped air, our versatile
Blocker PurgeAir Dry Sack resists ballooning to help maximize use of
space within a pack or bag. Plus, the fully waterproof construction
ensures essential contents are protected.

Versatile materials: Lightweight 70D polyurethane-coated nylon materials
are a tougher, more resilient cousin to the ultralight BlockerLite
materials. More durable and versatile, these materials are great for
all-around use with confident waterproof protection.

PurgeAir™-equipped: Our unique and waterproof PurgeAir valve vents
trapped air, helping the sack compress further after being sealed, and
is both more durable and more reliably waterproof than
waterproof/breathable fabric membranes.

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.
