Triathlon, especially long course, is hard enough. Deciding which top to wear shouldn't be, but when you start looking there seem to be endless options. The TYR Competitor Singlet's more generous cut is ideal for ultra endurance events where comfort might just trump aerodynamics. For the construction of the singlet, TYR used its Competitor Woven fabric. This is a lightweight, high stretch fabric that conforms to your body to minimize drag during the swim. At the same time, it's quick drying so you won't remain soggy during the bike leg. It also has a UPF rating of 50, which means that it will help to keep you shielded from the sun's rays. Once dry, the top wicks moisture away from your skin to keep you continuously dry. The singlet is form fit but features low arm openings and a deep scoop neck to minimize chafing of skin. A 10in zipper allows you to quickly dump heat when the need arises, while a single back pocket holds a few gels to keep you fueled on the run. The TYR Competitor Singlet Men's Top comes in sizes X Small to X Large and is available in Blackyellow and Blackred.
