The big story of what gets us so enthused about Castelli's Body Paint 2. 0 Women's Shorts is what they don't have namely, seams. Rather than playing Frankenstein with multiple panels of different materials in different spots, Castelli uses a single, wrap around piece of fabric that itself changes over the body of the shorts, making for a fit that all but disappears in the saddle. The legs benefit from a dimpled, aerodynamic finish, strategic areas are built to promote breathability and wicking, and the entire, single piece body provides gentle compression to reduce fatigue caused by road noise. The two spots where Castelli did opt for stitching make sense and seem for now, at least unavoidable: the waistband and chamois attachment points. The waistband is a swathe of keep the shorts up material, which complements the lie flat, integrated leg bands for a secure fit. The chamois is Castelli's Progetto X2 Air insert, which incorporates perforations and antimicrobial properties throughout its multi density padding to protect against bumps in the road, moisture build up, and bacteria.
