Blockerlite Compression Dry Sack

Maximize packing and storage efficiency on your next river trip while keeping all of your gear bone-dry with the new SealLine Blockerlite Compression Dry Sack. Constructed with featherlight fabrics, this dry sack protects your gear from splashes and submersion alike while barely adding to your weight totals. Its Continuous Compression system with a PurgeAir valve reduces volume so you don't waste an inch of space, and the PackTight shape features flat, rectangular sides that let you nestle multiple bags as closely and efficiently as possible. Save space and shave weight without sacrificing a modicum of protection with the Blockerlite Compression dry sack.
