Sneak through the water, slip past the wind.
One could argue that the combination of aero- and hydro-dynamic properties will make or break a pair of triathlon shorts, and possibly the race. Essentially, it comes down to managing airflow, and coincidentally, the human body accounts for over 90% of aerodynamic drag on the bike and 100% of hydrodynamic drag during the swim. Castelli lives up to its reputation for creating wind-slicing kit with the Women's Free Donna Tri Shorts. By pairing a nearly seamless design with a low-profile, compacted thread Lycra, the Free Donna is nearly invisible to air and water, which, in turn, makes you faster.
The integrated leg grippers don't feel like they're binding your legs, as some grippers can. They hold your leg subtly, so you don't notice them as you ride, run, or swim. Castelli achieves this effect by knitting the grippers directly into the fabric at the hem, so everything lies flat and gently grips your leg without binding or creating transitional ridges to create drag by catching wind or water.
Castelli's triathlon-exclusive KISS Tri chamois rounds off the shorts. Castelli designed the KISS Tri to work most effectively while your hips are rotated forward in an aero position on the bike while trimming unnecessary bulk to optimize comfort during the run and swim portions of your race. The removal of excess thickness also allowed Castelli to make the pad wider, thus moving stitching away from the more sensitive areas to avoid irritation. A liner on the front of the shorts adds support to make you more comfortable during the run.
