Castelli Insider Jersey

Our lightest jersey ever is perfectly designed for your future esports challenges. Indoor training has never looked so good. We designed this jersey to withstand the rigors of indoor training. Its 3D mesh material allows for maximum airflow for cooling while simultaneously wicking moisture away to keep your skin dry. We made sure the jersey isn't too see-through, so it can be worn during group training sessions. Thanks to its long zipper, it’s easy to take off, for example, after warming up. The two back pockets can hold AirPods, a phone, a headband, or anything else you might take to training. The collar is low and the waist is kept short to ensure maximum cooling. This jersey is also a great option on hot summer days.

Lightweight, quick-drying 3D mesh material (93% polyester, 7% elastane) for optimal sweat management. HeiQ Fresh Tech silver-free treatment. Material with good airflow without being too transparent. Full front zipper. Two back pockets. Can also be used outdoors as a jersey in hot weather.
