Castelli Pro Issue Short Sleeve Cycling Base Layer - SS23

The Castelli Pro Issue short sleeve cycling base layer, as its name suggests, is worn by many of Castelli’s professional cyclists and was originally developed following requests from them for a base layer that performed well in those ‘in-between’ weather conditions where riders experience a wide variation in temperatures.

The Pro Issue base layer keeps its wearer warm but also helps to move moisture away from the surface of their body; with a clever 3D mesh-fabric the Pro Issue short sleeve cycling base layer creates dead air space next to your skin to help insulate you from the cold while the polyester capillary action moves sweat away making this base layer perfect for training and racing during the more changeable seasons.



  • 100% polyester 3D mesh fabric
  • Reduced seaming at shoulders for extra comfort
  • Wider collar to fit under aero jerseys
  • Flat waist hem to lie flat in shorts
  • Suitable for a temperature range of 15o -  25o

Castelli Size Charts

Andrew Good fit (slim as expected). Comfortable, wicks well, V. lightweight. Expect it to last and wash well with care
Michael Great product that I have come to expect from Castelli. Works well under a jersey to wick away moisture. I thoroughly recommend this base layer.
Mr Gen Ka While winter in Canada, I use it at home when I make my roller. Works great. For indoors I like base layer more than jersey. I ordered Large size. Height 176.5 cm, weight 75.1 kg
Cesar Perfect as a base layer for my Castelli mid weight jersey in cool conditions!
Mr Brom Breathable and comfortable
Mrs nevies Size comes in a bit small (usually I`m a M, here L/XL). Very lightweight, barely realize it's on you.
Jan Great baselayer, light and airy not too warm. Tight fit but thats intentional.
Mr Davis This base layer is perfect for early fall or late spring rides. Wicks moisture away very well and adds a little extra warmth when needed. Kind of expensive, but worth it.
Richard B Work very well to control moisture - this is my second one. The sizes are very italian ! I need a large which is at least one size bigger than normal.
BOOBIER Thinner than the Prosecco base layer. The sizes are quite small so check sizing carefully - I'm fairly small and needed a large which is still a skin fit.
