A total of six D-rings are located on the sides of the bags to allow other items to be attached to the bags if desired. Both bags are made with 1680 denier waterproof fabric. A rain cover comes standard.

Backpack Function: Shoulder straps are secured on the backside of the main compartment bag by way of elastic sleeves. The shoulder straps are placed into service by pulling them from the elastic sleeves and snapping the bottoms of the straps to the D-rings on the side of the bag. The attached adjustable compression straps connect to the quick release buckles on the backside of the top bag.
