The WYN republic sleeveless triathlon top is where it all starts. (Ombré top in picture for example of the fit/fabric of this tri top as the sketch doesn't do it justice)
Constructed from the finest textiles optimizing breathability, flexibility, quick-dry technology and aerodynamic properties. The fabric is highly water repellant, making this the perfect top to wear on its own in a triathlon- no wetsuit or speedsuit required (but don't forget the shorts!).
