Innovative compression maximizes limited hatch space.

Designed to use in cramped boat hatches, the Blocker Series bags boast flexible, easy sliding materials, air-venting valves, and hatch-friendly shapes to make the most of limited boat storage space—all while providing our renowned waterproof protection.

The Bulkhead Compression Dry Bag features our Continuous Compression system and PurgeAir™ valve, offering fast, easy, and reliably waterproof compression to maximize space in tight boat hatches.

  • Stow Friendly: Use as a liner for 10L bags.  Made of durable materials that help the bag slide smoothly in and out of boat hatches.
  • Waterproof: Constructed with 100% lightweight waterproof materials and confident closures to deliver protection in wet environments. 
  • PurgeAir™ Equipped: Waterproof, air-purging valve compress bag further once sealed.
  • Tight, Simple Sealing: DrySeal™ roll-top closure makes it easier and more intuitive to achieve an optimal seal.
  • Durably Constructed: Fully welded seams result in stronger, more durably waterproof construction compared to sewn-and-taped seams.
  • Smarter compression: Unlike conventional systems that pull against seams, our Continuous Compression system encircles the bag to minimize seam strain, maximizing durability for dependable protection.
  • Oval bottom: Shape keeps bag from rolling around and makes it easy to store, stack, and pack.
  • Materials: 70D/140D 7.5 oz polyurethane-coated ripstop nylon body
  • PVC-Free: Materials have a reduced environmental impact over vinyl-coated materials.
