Castelli Insider 2 Short-Sleeve Jersey - Men's Black/Dark Gray, XL

The lightest jersey we've ever made. Great for indoor riding but also perfect for those hot summer days.We made this jersey for the rigors of indoor training. The 3D Mesh fabric allows maximum airflow for cooling while wicking away moisture to keep you dry. We made it on the limit of not being too transparent, in case you want to wear it for group training sessions. Or if you're using it at home and want to take it off after warming up, the long zipper means it comes off easily. We put a couple of pockets on the back so you can stash your AirPods or phone or headband or whatever you haul to your training station. We've kept the collar low and the length short for maximum cooling. It just happens to also be a great hot-weather jersey that you'll pull back out come August.
