Triathlon Jerseys

Triathlon jerseys are designed to be as aero and lightweight as possible, whilst being comfortable so you can focus on the task at hand - dominating the race. Fast wicking, quick drying properties as well as plenty of ventilation are all common features of triathlon jerseys.

If your tri event will be in the heat, then look for lightweight jerseys that offer sun protection (UPF 30+ is ideal). Look for sleeveless jerseys when the temperature really rises or a seamless design for a smooth feel against your skin. Jerseys with a compressive design help to support your muscles when you’re working at maximum effort. We stock both men’s and women’s tri jerseys from some of the biggest brands.
