When we introduced the PASSPORT - the feedback from our Team riders, Retail partners, and the conversations we 've had in the liftlines (Whattup Alpental and Brighton Locals?!) - we knew we had a winner. The waist width, sidecut, camber profile, and taper were spot on - but some riders we spoke to were looking for something a bit more robust for higher speeds and steeper terrain, and we said ... "let 's make some prototypes. " We did, they were okay, so we made some more, and some more, and they f#cking ruled. The result of proto round #3 ... the COMMONWEALTH - using the same shape and geometry that has made the Passport successful, with a more "beefed up " feature set for riders looking for something a bit more demanding. Our A1 Core gets wrapped in a heavier weight tri-axial fiberglass, which is then layered in our patented Spectral Braid (TM) - a piece of technology that we developed that allows you to fine tune the tip-to-tail flex of the snowboard independently from the torsional flex - it rules, we promise. We topped it all off with a wax infused sintered 4001 base to make sure you 're not getting stuck in the flats. We believe that everyone should be able to experience the mountains - so the Commonwealth was designed and tested for all-genders. Starting at a 146 and sizing all of the way up to 163-, this snowboard 's construction, waist width, and flex profile is scaled to meet the needs of the riders for each respective size.
