The Back on Track leg warmer are made with our iontex® technology. Made with a soft 4-way stretch fabric for extra comfort and silicone grip at the top to ensure that they always stay in place during the ride. Easy to put on and to take off during long rides. Breathable material with quick drying properties. May protect lower thigh, knee and calf against cold during rides and may help to reduce discomfort in the area between thigh and knee which is highly exposed during cycling. If you need extra support we recommend our popular knee brace with Welltex® technology.
