The Cadence Tight is designed for aerobic activity... trail running, cycling, cross country skiing and snowshoeing. It's special because the front is made of windproof stretch fleece while the back is made of 100 wt. low bulk stretch fleece. The result...wind protection and insulation in the front where you need it while stretchy with low bulk in the back. If you like getting out no matter what the weather then the Cadence is the ultimate cold weather tight for you.
