See available dry bags


Reliably waterproof, but not wildly heavy, these dry bags slot smoothly into small spaces. Rectangular shape leaves less wasted space in your pack. Great for backpacking, cycle touring, kayaking or travel.

  • Made from 70-denier polyurethane coated nylon ripstop that offers more puncture and abrasion resistance than PVC
  • Radio frequency welded seams are stronger and more durably than sewn and taped seams
  • Roll-top closure seals tight
  • One-way PurgeAir valve vents trapped air while remaining waterproof so you can compress the bag
  • PackTight flat-side rectangular shapes nestle close to together so there's less wasted space
