The Mountain Wedge Expandable is the ideal wedge for the rider who occasionally wants to carry extra gear. The three-point suspension system is similar to the Wedge II, with a side-release buckle on the main strap for easy access, and hook-and-loop material on the sides for added stability and load compression. The main strap provides support in both closed and expanded modes; there is even plenty of leftover webbing to stash a lightweight jacket under the bag. A small flat pocket on the underside of the bag is perfect for keys or a few dollars.
When more space is needed, the gusseted bottom unzips to increase the volume of the bag from 115 to 175 cubic inches. The HDPE stiffener adds additional strength and stability to this large wedge, which also features stealth zipper heads and 3M Scotchlite Reflective Material, to which a light can be attached.
