Our mens triathlon tops are designed to be worn throughout an entire triathlon race. When looking for a triathlon jersey you should consider the fit of the tri top. All of our tri tops for men are a little snug. The form fitting tops (FX Triathlon Tops) are more aerodynamic, while the looser tops (FRT Tri Tops) are better for the beginner triathlete who prefers a looser fit. All of our mens triathlon tops have small pockets for nutrition storage. Our FX triathlon jerseys are made from fabrics that actually help to cool your body and are made of quick drying materials.
