Full waterproof protection with a simple roll-top closure, SealLine's Blocker Dry Sack provides resourceful adventurers an efficient-packing shape to optimally organise and protect essential clothing and gear inside a pack.
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
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 organisation
