The right triathlon bottom depends on your race format and personal preference. For the swim leg, a swimskin or speedsuit — like those from Orca and TYR — adds a compressive, hydrodynamic layer without the bulk of a wetsuit. Tri shorts are the most versatile option: the chamois is thinner than a road cycling short, so it performs on the bike without becoming uncomfortable during the run. Run shorts and skirts suit athletes who prefer lighter coverage after T2, while compression tights and capris work well for sprint-distance racing and long-course training in cooler weather. The right choice often comes down to the distance you’re racing and how much you prioritize bike comfort versus run freedom.
