The skin track demands a lot. So does the couloir on the way back down. The Tour Shell Bib pairs perfectly with the Tour Shell Jacket - stretch elastic bib and suspenders move with you on the climb, inner thigh venting keeps you regulated when the pace picks up, and back venting handles the rest. Built for full days in the mountains, not half ones. Filled with technical details to handle the most demanding route and everything you take with you. A true-to-size athletic fit designed to move with you.
