Assos Spring Fall Leg Warmers Late autumn and early spring welcome some of the best riding of the year; the oppressive heat of summer has gone, or the bite of winter has finally relented. And it's here that the Assos Spring Fall Leg Warmers excel. Cooler temperatures still require some concessions to keeping warm, and the mid-weight insulation of these warmers ensures muscles don't suffer and seize up. The ultrasoft and flexible fabric is super-comfortable for smooth pedalling, and fast-drying too, preventing moisture from causing a chill after an injection of sweat-inducing pace.
