SealLine’s most versatile, feature-rich pack sack, the Blocker Compression Dry Sack, saves space on paddle and trail adventures, while the watertight valve quickly deflates the trapped air to help with compression. The fully waterproof construction ensures that the equipment remains protected and can be properly transported.
Lightweight 70D polyurethane coated nylon materials are the more robust, more resistant relatives of the ultra-lightweight BlockerLite materials. These materials are more resilient, versatile and perfect for reliably waterproof protection.
Unlike traditional systems that pull the seams, our compression system wraps around the bag with two equally strapped straps to minimize seam stress and ensure long-lasting protection.
SealLine’s unique, waterproof PurgeAir valve deflates trapped air, further compressing the dry bag after closing. The valve is more reliable than waterproof / breathable tissue membranes.
Roll-top closure with wrinkle-free stiffening strip for secure closure of the pack sack.
Fully welded seams provide better and more durable protection than stitched or glued seams.
PackTight packs are characterized by their flat, rectangular shape, which is space-saving stackable and packs 20% more efficiently than round transport bags.
- Material: 70D nylon with polyurethane coating
- Roll closure with wrinkle-free, double sealing technology
- Thanks to the watertight air outlet valve, the bag can be compressed even smaller after closing
