Castelli Insider 2 Jersey

The lightest jersey we have ever made. Ideal for the gym, but also perfect for hot summer days.

We designed this jersey to withstand the rigors of indoor training. The 3D mesh fabric allows for maximum air circulation for cooling while also wicking moisture away to keep you comfortably dry. We made it so that it is not too sheer in case you want to wear it during group training. On the other hand, if you want to use it at home and take it off after warming up, the long zipper makes it a breeze. On the back, we added a couple of pockets where you can store your AirPods, phone, headband, or anything else you don’t want to be without during your workout. We kept the collar low and the length short to ensure maximum cooling. Plus, it’s a great jersey for warm weather that you’ll want to bring out again in August.
