Castelli - Insider Sleeveless - Men's - DarkRed - 2024

Castelli - Insider Sleeveless - Men's - DarkRed

We've made this sleeveless top to actually cool you more than not wearing a top at all. It works because it will spread out sweat over a wider area to aid in evaporative cooling. Of course, it's not going to make your indoor sessions sweat-free, but it will make them more comfortable. It's intentionally simple and is cut close to body, and there's a pocket on the back. We finish it with the HEIQ Fresh Tech natural odor-control treatment that prevents odor buildup in the garment over time.


3D Mesh lightweight 93% polyester / 7% elastane wicks moisture and dries quickly

HEIQ Fresh Tech silver-free odor-control treatment

Semi-open mesh allows maximum airflow and cooling
