Sealline - Blocker Dry Compression Bags

Sealline - Blocker Dry Compression Bags, bag with compression system

Sealine's Blocker Compression Dry Sack saves space on paddling and trail adventures, while the waterproof valve quickly vents trapped air for easy compression - all this with a fully waterproof construction ensures essential contents are protected, condensed and organized.
It is the most versatile and feature rich packaging system bag.

Features
Versatile Materials: Lightweight polyurethane-coated 70D nylon materials are a tougher, more durable cousin to ultralight BlockerLite materials. More durable and more versatile, these materials are perfect for all-round use with secure waterproof protection.
Smarter Compression: Unlike conventional systems that pull against the seams, our continuous compression system surrounds the bag to minimize seam strain while maximizing durability for dependable protection.
Featuring PurgeAir™: Our unique, waterproof PurgeAir valve vents trapped air, helping the bag compress further after being sealed, and is both more durable and more reliably waterproof than waterproof/breathable fabric membranes.
Waterproof Closure: The roll-top closure features a crease-free stiffening strip to ensure a secure seal when closing the dry bag.
DURABLE CONSTRUCTION - Fully welded seams result in a stronger, more durable protective construction than stitched and taped seams.
Efficient Packing: PackTight™ Packing System bags feature flat-sided rectangular shapes that nest close to each other, packing 20% more efficiently than rounded bags for easy, space-saving organization.
