Blocker Dry Sack - Gray


Product Sizes


Featuring an efficient-packing, patent-pending rectangular shape and strong fully welded seam construction, Blocker waterproof dry sacks are the easiest way to organize and protect clothing and gear in your pack, luggage, or on a boat.
  • Space-saving: Patent-pending rectangular shape packs 20% more efficiently than rounded dry sack shapes, saving space in your pack. 
  • Efficient-packing: PackTight™ packing system takes advantage of the flat-sided, rectangular shapes of the Blocker dry sacks, closely nestling them together for easy, space-saving and intuitive organization. 
  • Waterproof strength: 50% stronger than sewn and taped seams, all seams are welded to deliver superior strength, durability, and waterproof protection over time. 
  • Tough: High-strength 70-denier polyurethane-coated nylon is light enough to satisfy ounce-counters, yet durable enough to stand up to life outside a pack. 
  • Eco-friendlier: PVC-free materials offer a reduced environmental impact over vinyl materials. 
  • Secure: Roll-top closure features a grippy stiffening strip to ensure a wrinkle-free, secure seal when closing the dry sack. 
  • Easy organization: Available in 4 colors and 5 sizes, making it easy to organize by both dry sack color and size.
