SEALLINE - Blocker PurgeAir Dry Sack

Featuring a waterproof valve that purges trapped air, this versatile, fully waterproof Dry Sack resists ballooning to help maximise use of space within a pack or bag.
• Versatile materials: Lightweight 70D polyurethane-coated nylon materials are durable and versatile and great for all-around use.
• PurgeAir™-equipped: The unique and waterproof PurgeAir valve vents trapped air, helping the sack compress further after being sealed.
• 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.
• Dimensions: 16 cm x 30
