POC's Multi D Women's Short Tights, are, technically speaking, shorts, but we agree that short tights sounds more technical and the Multi D are certainly more advanced than your average cycling shorts. Not only do they manage to combine an ergonomic four panel design, supportive compressive fabric, and a breathable construction into one lightweight package, but they pack a women's specific Multi D WO chamois in as well, giving you supreme comfort when you're in the saddle. The chamois has pre cut, silicone based VPDS inserts that provide anatomically mapped support and top class breathability, while the compressive fabric reduces muscle vibration to ward off fatigue and speed up recovery. Silicone leg grippers keep the Multi D from riding up the legs are slightly shorter than those of the Multi D WO Bib Shorts, incidentally, and a high rear waistband provides full coverage when you're in an aggressive riding position. POC also integrated a reflective print for added visibility in low light conditions, so it won't be quite as hazardous if your ride keeps you out until twilight.
