The Mountain Wedge II has been completely redesigned with easy access in mind. Our standard top-quality, double-head zipper circles the entire end of the bag so the entry door hinges open, revealing a flat zippered pocket in the door. A "U"-shaped HDPE stiffener supports the bag, and an additional flat pocket on one side of the bag provides convenient storage for your keys and money. A strip of 3M Scotchlite Reflective Material is sewn across the end of the bag and accommodates a rear clip-on light for added safety. The MWII attaches to your bike with our ultra-secure, three-point suspension system: a 1" piece of webbing runs through the seat posts and around the bag. A 1" side-squeeze buckle holds the bag securely, and to prevent drift, there is a 1" hook-and-loop stopper at the bottom of the bag.
