The same main compartment as the MBHP2 & 4 but without the bells or the price. The large main compartment derives its shape from a stiffener with dual zipper heads, covered by a storm flap. Mesh pockets on both side allow storage of small quick access items. Mounting is simple and secure: cinch the two top 1" webbing tails across the handlebars and tighten with the 1" tension locks. Next, secure the lower webbing around the head tube. For night safety, we have added a strip of high-visibility 3M Scotchlite Reflective Material.
