With the hot weather, a lightweight sleeveless base layer like the Castelli Pro Mesh provides wicking without extra insulation to stop airflow through the fabric. It’s made of a very airy mesh, with the spots being almost transparent, so it adds little to heat build-up as you ride. It’s very soft too and with flatlocked seams you won’t find it uncomfortable – of even notice it’s there most of the time.

As a change from the usual white, the Castelli Pro Mesh base layer comes in a range of four printed oblique dash patterns. The orange is particularly bright and redolent of warm rides – it cheered me up just getting it out of the drawer. As well as lime green and light blue, there’s a grey option so you can tone it down if you want to.
