Why We Like The Castelli Insider Short

The Castelli Insider Short is a lightweight, breathable short built for spin class or catching a few Zwift miles with your pals when it's too cold for a coffee ride. They feature a thin Lycra main body with mesh side panels for added ventilation, raw-cut leg endings to ensure a secure fit, and an extra comfortable chamois for optimal seated comfort.

I tend to forget that Castelli runs small. I ordered a large and felt a little tight than my other large bib shorts. Given the chance again, I would go with the XL. Feels nice and cool though, perfect for indoor training!
