Seal Line Blocker Lite Compression Dry Sack - 5L

Super-light compression sacks that have welded seams and a roll top to make them fully waterproof. A purge valve let you push out extra air to compress them. Light enough for bike touring or backpacking, but maybe not so durable that you'd want to use them as portage bags.

• Made from featherweight 20-denier silicone and polyurethane-coated nylon ripstop.
• Radio frequency welded seams are stronger and more durably waterproof than sewn and taped seams.
• One-way PurgeAir valve vents trapped air while remaining waterproof so you can compress the bag.
• Internal roll top closure is easy to use and seals tight.
• 4-strap Continuous Compression system encircles the bag to minimize seam strain while still letting you compress your load.
• PackTight shape features flat-side rectangular shapes that nestle close to together so there's less wasted space.
