Sea To Summit Hydraulic Dry Bag

The Hydraulic Dry Bag is the burliest dry bag we make. It's designed for demanding conditions where rough and tough treatment is to be expected. The 600D heavy duty abrasion resistant TPU laminated fabric and RF welded construction throughout give the Hydraulic its superior strength. The interlocking non-wicking roll-top makes it easier to close, and RF welded lash loops provide secure attachment points. Plus an oval base means the dry bag won’t roll away when you set it down. All models use our Field Repair Buckles, which can be replaced in seconds using a Philips screwdriver.
