Rather than worry about choosing tri separates to race in that will achieve the right fit and pair well together, you can simplify race day by investing in a one piece suit like 2XU's Compression Full Zip Sleeved Tri Suit. Tri suits offer a streamlined, contoured fit without the chance for gaping fabric, tops riding up on the bike or run, or uncomfortable waistbands, leaving you to focus on racing and not on distracting fit issues. Shaped with smooth, 105 denier fabric, the Compression Full Zip Sleeved Tri Suit provides allover support to your hardworking muscles, using graduated compression from your legs to your shoulders 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 it added an ICE X CT proprietary treatment to the fabric that gives it a UPF 50 rating to shield your skin on courses with little shade. As the temperatures rise through the morning, the full length zipper allows you to add ventilation, while the medium length 8in inseam length on the shorts provides a versatile fit. Finally, 2XU included 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 its 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.
