Magic! The next generation ASSOS S5 full-length bibtight for cold Winter riding conditions. It features warm ASSOS RX_Plus and wind blocking stratagon airBlock membrane fabric inserts where you need them most. Available with or without an ASSOS S5 insert. Why? Without an insert, you wear your regular ASSOS shorts underneath. Then, when temperatures drop even lower, wear your ASSOS knicker as a first layer, for WinterPlus riding.
