When sport is part of your daily life, and you spend all your weekends outdoors, you need the right kind of base layer - a high performance base layer like the CROSSTRAIL PEAK LONGSLEEVE. This functional top is a true all-rounder and is suitable for indoor or outdoor training. As soon as you slip it, on you'll appreciate just how soft and comfortable it is. It is super breathable too, of course, and dries quickly after those sweaty sprints. The fabric's stay-fresh properties reduce unpleasant odours.
