As athletes, we're always looking for ways to be a little bit more aerodynamic for faster times on race day. Enter the 2XU Project X Men's Tri Suit, with supportive compression and a streamlined fit that eliminates the potential for flapping fabrics, bunching tops, gaping waistbands, and other wardrobe worries, letting you focus on getting to the finish line.Shaped with smooth, 105 denier fabric, the Project X Tri Suit provides allover support to your hardworking muscles, using MCS Compression Technology to help limit muscle oscillation and lessen fatigue as you spend hours on the course. 2XU carefully designed the sleeves to reduce drag on the bike, and adds three aerodynamic pockets across the back for stealthily toting snacks. An overall UPF 50 rating shields your skin on courses with little shade, and a full length zipper pairs with Sensor Mesh X technology promotes additional cooling airflow as the temperatures rise. 2XU includes its Memory Tech LD chamois, a model designed specifically for time trials that features plush cushioning placed strategically to support you best while you're stretched out over aero bars. Though it's supportive, the chamois still maintains a slim, flexible profile that won't inhibit your freedom of movement when you hop off the bike and onto the run course.
