The Mid base layer is designed for less extreme winter
conditions than its "Heavy" counterpart. Ideal for those crisp
autumn and early winter days.
Polartec PowerWool gives you the best of both worlds, with a
soft, odour-resistant inner face and a tough, high-wicking
synthetic outer face.
Highly breathable, with an inner grid pattern helping to trap a
thin layer of air to maximise insulation efficiency and control
moisture. As with all PNS base layers the fit is snug (as it needs
to be to work effectively) but a good amount of stretch is built
in, ensuring comfort and unrestricted movement on the bike without
bunching under outer layers.
