Castelli RS Superleggera jersey review

Designed for searing hot days at the height of summer, the Castelli RS Superleggera jersey is one of the lightest short sleeve jerseys produced by the Italian manufacturer. However, not quite the lightest, a title which goes to the 93g Climber's jersey 2.0, 11g lighter than the RS Superleggera.

As you would expect at that weight, there's not much to the Castelli RS Superleggera jersey. The fabric is incredibly light and airy, so much so that half of the time you almost forget that you've got it on. The good news (for onlookers) is that because of the darker colours that this jersey is produced in (black, red, and green) it is not see through.

Another feature of this jersey is the rear 'tail' that finishes the back design under the pockets. Used on warm but not hot day (20ºC), the black colour tended to be a bit too warm to be worn under the sun (but the red or the green ones can work better).

Watch: how to dress for hot conditions

As you would expect from any half-decent jersey, the Castelli RS Superleggera jersey features three open rear pockets as well as a zipped security pocket for keys and cards etc.. The pockets are of a good size, meaning that you will be able to take everything you need for long rides at the heigh of summer. However, as this is quite a light jersey, they are prone to sagging and bouncing around a bit when fully laden.

Finally we come to the price, which at £100 means that you are basically paying a quid for every gram of this jersey (but at least means that bigger riders are getting better value for money). Clearly this is a lot of money to spend on a cycling jersey, but given the technical nature of the Castelli RS Superleggera jersey and its excellent performance in hot weather, it might be a price worth paying.
