Castelli Principessa Short

This is Castelli's top womens short that features a standard panel construction. Each of these panels are made from 200 gram action Lycra, so you get nice compression without a binding and restrictive feeling. They also include the best womens chamois insert and a unique waist band that elevate the Principia into the stratosphere where comfort is concerned. Ride and lounge in them all day or race in them, they are that versatile. It's no wonder these are best sellers with each passing season.

The 220 gram Lycra composition used in each panel straddles the perfect balance of compression and comfort. You end up with enough compression for muscle support and good blood flow, without the heavy compressive and restrictive feel. There are 8 panels total, each of which are anatomic, so you get an exacting womens fit. The combination of 220 Lycra and this anatomic fit, you end up with a tailored-like garment. The Soft Touch waistband is a sheer act of brilliance. It has a yoga style back with an elastic front stretch panel. It's similar as the design on the Body Paint 2.0 Womens short, and we have yet to find a better design. GIRO3 soft touch leg grippers stop the shorts from moving around while you're pedaling but will not bind or cut circulation.

The Principia gets Castelli's womens specific X2 Donna chamois, which is widely considered the best in the business. It features two distinct components. A skin care layer which is bacteriostatic, soft, stretchy, seamless and is designed to prevent chafing and a cushioning layer that features variable thickness with extra viscous padding beneath the sit bones and perineum.
