Our Flexair Pro Fire Alpha® Pants bring the best in performance to your next run. With a run as hot as yours, you’ll also be grateful for the breathable, Polartec® Alpha® insulation to keep you cool—no need to keep removing or adding layers as you shred—while the DWR finish sheds moisture, dirt, and debris like a champ. Featuring a tapered fit for superior mobility and to reduce snag, they come with Dyneema® knee and leg panels to increase abrasion resistance and provide enhanced flexibility. That range of mobility is also assured thanks to trusted TruMotion® all-way stretch fabric, which is lightweight and durable and won’t weigh you down as you pedal your way along the trail. Ventilation and breathability come care of body-mapped laser perforations on the front and rear panels, while the mesh on the back of the leg also ups the cool factor.
