Blockerlite Compression Cinch Sack

The SealLine Blockerlite Compression Cinch Sack caters to ultra-light backpackers and long-distance paddlers shaving every last gram and reducing bulk from their set-ups. Silicone, PU-coated nylon fabric repels rain showers and prevent splashes from dampening your precious items inside the cinch sack.

Not only is it water-resistant, but it features Continuous Compression that packs your sleeping bag, clothes, and other items down to a small size, but without placing undue stress on sensitive seams, so it'll last much longer. The drawcord closure makes it easy to grab and stash items on the go and welded seams result in a stronger, more durable sack. Additionally, you'll notice its flat-sided design packs 20 percent more efficiently than comparable rounded sacks.
