Compatible with all multiday and expedition SG Packs, the new 500 cubic inch Hydro Lid offers dual compartment storage with front and back zippers to give you added organization and functionality. The lid can also be converted to a large singular compartment by removing the internal Velcro dividing wall.

Another unique feature to the Hydro Lid is its ability to be detached from the bag and ran as its own attack-size pack - where only the essentials are needed - using the detachable Stone Glacier shoulder straps from any Stone Glacier frame. The lid also incorporates a hydration port to facilitate hydration storage.
