The ASSOS UMA GTV Spring/Fall Bib Tights C2 keep our body temperature regulated as we spend the winter riding outdoors. The Osmos Medium fabric offers insulation with thermoregulation, dumping excess heat while keeping our legs comfortable and supported. To keep the shock-absorbing dual-density chamois pad and body panels exactly where they need to be, ASSOS incorporated an X-frame design with a rollBar bib strap suspension system and bisiClick magnetic closures.
