BlockerLite™ Dry Sack


Fully waterproof with minimal weight, our ultralight and uncomplicated BlockerLite Dry Sack boasts an efficient-packing shape to optimally organize and protect essential clothing and gear inside a pack.
  • Ultralight: Featherweight 20D silicone- and polyurethane-coated nylon delivers waterproof protection while barely tipping the scales.
  • Waterproof closure: Roll-top closure features a wrinkle-free stiffening strip to ensure a secure seal when closing the dry sack.
  • Durable construction: Fully welded seams result in stronger and more durably protective construction compared to sewn-and-taped seams.
  • Efficient-Packing: PackTight packing system sacks feature flat-sided, rectangular shapes that nestle closely together, packing 20% more efficiently than rounded sacks for easy, space-saving organization.
