Assos' warmest winter bib tights, the Winter Bib Tights w/Chamois, allow you to ride outside when everyone else is on the trainer! Strategically-placed airBlock 851 panels protect you from wind while insulating key muscles. The AEPD ergonomic cut provides total freedom of movement, while Assos' wicking RX fabric on the thighs and knees keep critical areas warm and dry. You'll also love the front zip, stirrups that seal out cold air, and the reflective accents for safety. Plus, these tights have the Assos high-density chamois with Elastic Interface Technology that moves with you and eliminates friction so you feel great on your longest rides.
