Why do you need a base layer? Well, apart from looking much cooler than a t-shirt, a functional base layer is an essential bit of kit for a couple of reasons:

1. Use it for extra insulation under a jersey when it's slightly too cold for a jersey alone but not cold enough for a jacket.

2. Wear a base layer on its own when training inside or at the gym. Its moisture-controlling properties means that even if you get a sweat on you’ll stay more focused, as the fabric has a sweat-wicking effect which aids cooling.

Our base layers have a moderately opaque front panel and a mesh rear. The mesh rear provides insulation when worn under a jersey by trapping air, but will also aid cooling when worn on its own by allowing body heat to escape more easily.

Available in black & white.
