Designed to be worn under TSG MTB riding apparel and made from fleece lined Spandex the Thermo Bib Pants base layer delivers warmth and comfort for cold in-saddle sessions. The bib features an integrated, ergonomic dual-density chamois to maximise saddle time, while the shoulder straps and the upper back are made from a fine vented mesh for the perfect body comfort from hill climbs to fast descents. There is also a short front zip and ankle zips for easy dressing and a lumbar pocket for essentials and other devices.
