Castelli Pro Issue Sleeveless Cycling Base Layer

The Castelli Pro Issue sleeveless cycling base layer was developed in direct response to requests from professional cyclists for a base layer designed specifically to perform in mid-temperature conditions of 15o to 25o when they’re looking for a base layer that doesn’t add warmth, rather it provides moisture wicking properties. By moving moisture away from the surface of your skin the Castelli Pro Issue sleeveless cycling base layer keeps you feeling dry and fresh under your race jersey.

Sizing Information for Castelli Clothing:
Castelli Size Charts

Really good one, I was worried if size will fit but size guide tells the truth
Lightweight, but a bit small, I suggest you buy one size up
Good fit and breathability. Allows me to go for morning rides in the Middle East winter without the need of a gillet
A good base layer that is very light weight. Does the job it is supposed too, wick sweat and dry quickly. Form fitting, be carful when putting this on so you do not stretch out the seams as the fabric has no give like some other base layers.
