Mavic Cosmic Pro jersey review

The Mavic Cosmic Pro jersey is Mavic's ultra-light climber’s jersey for hot weather riding in the mountains. Mavic clothes the JLT-Condor professional team and says it has worked with the team’s riders to test prototypes and come up with the final design which many members of the team wear to race in. It’s part of Mavic’s sub-kilogram complete race kit and comes in at 156g for a size medium, with Mavic claiming that it’s the company's lightest ever race jersey.

It’s made of three different fabrics. The front panels of the jersey are made from Mavic’s proprietary 37.5 knit, a very open mesh fabric, which the company claims is five times more effective than normal polyester at wicking away sweat due to the high surface area of its yarn.

The sides and shoulders are made of a more densely woven material with a lot more stretch for a good fit and higher UV protection. The rear of the jersey is different again: slightly more open than the side panels with more sideways than vertical stretch. This means that it does a really good job supporting the three rear pockets – one of which has a reinforced headphone wire hole.

The yellow sleeve grippers are single layer and fit closely without being constrictive, while the collar is high and also a close fit. The hem gripper is wide and has silicone dots to keep it in place.

The end result is a jersey which is fits really nicely; it’s comfortable without any excess fabric and I experienced no windflap. It’s cool enough for hot weather riding, but if you do start to get hot, it’s easy to adjust the full front zipper on the fly too. Mavic offers the Cosmic Pro in four different colours and sizes from S to 2XL, so there are plenty of options available.
