Fasthouse's Fastline 2. 0 Pant offers all the durability we need to stand up the wear and tear of mountain biking. They're designed with 400D poly face fabric and 600D saddle fabric for enhanced abrasion resistance, and four-way stretch panels so we aren't missing out on freedom of movement. A zippered thigh pocket provides a secure space for essentials, and a short-length inner liner improves comfort.
