Merino Wool: nature's all-weather performance fabric.  Whether you are riding in the early morning or on a chillier day, it is valuable to have an extra layer like a sleeveless riding vest to keep the cold wind from your torso when you blast down your favourite trail. Easy to put on with its full body zipper on the side and without restricting movement, our lightweight Sleeveless Merino Wool Vest will help keep you warm without the bulk of a full riding jacket. We blended Merino Wool with Polyamide and Elastane to give you the perfect combination of comfort and durability. Merino wool has excellent properties for mountain bike clothing. It is soft, thermo-regulating and even keeps you warm when wet.
