  • 100% waterproof - KastKing's unique CycloneSeal closure system provides the ultimate waterproof seal. An extra layer of lining material temporarily bonds to itself as the top is rolled down and buckled in place, creating a complete seal to prevent any water leaks.
  • MILITARY GRADE Construction - Triple layer construction is up to 10 times stronger than other dry bags. The .65mm thickness is twice as thick as standard dry bags providing extreme puncture and abrasion resistance. Waterproof hi-vis interior PVC layer makes it easy to find your gear in low light conditions. Proprietary camo layer is puncture and tear resistant, and the exterior clear PVC layer is waterproof and abrasion resistant. High frequency welded seams ensure 100% weatherproof storage.
  • Molle Straps - Two rows of molle straps help to secure additional items to the outside of the bag. These handy attachment points can be used to clip on a sunglasses case, bluetooth speaker, phone, or other items for quick accessibility. These straps can also be used to lash your bag to a kayak, motorcycle, backpack, ATV, or anywhere you need (2 carabiners included).
  • ERGONOMIC Shoulder Straps - Two strategically placed shoulder strap attach points ensure the buckled roll top does not cause any back discomfort when fully loaded. Two removable shoulder straps help to spread the load evenly and reduce shoulder strain for a more comfortable carry. These heavy-duty nylon straps are durable, abrasion resistant and UV resistant. Heavy duty molded clips with a locking, spring-loaded stainless-steel closure, are designed to withstand the heaviest load.
