Core Short-Sleeve Tri Suit - Women's

What Our Gearhead® Experts Are Saying:

"The Core Tri W Suit is perfect for new triathletes. It’s lightweight, breathable, and has all the essentials like rear pockets and a KISS Tri pad that performs well on the bike and run. The raw-cut edges are a nice touch for added comfort and speed."

The Core Tri W Suit is Castelli’s ideal option for beginner triathletes or budget-conscious athletes seeking performance and comfort. Its lightweight, breathable fabric provides exceptional moisture management to keep us cool and dry through every discipline. The raw-cut edges on the sleeves and legs ensure an aerodynamic fit, while the GIRO4 flat leg grippers hold the suit securely in place without pinching.

The KISS Tri seat pad delivers targeted support during the bike leg but remains unobtrusive on the run, ensuring comfort across transitions. With two rear pockets for nutrition storage and a 3/4-length YKK® zipper for easy temperature control, the suit balances function and performance. Whether competing in your first triathlon or refining your race-day kit, the Core Tri W Suit ensures you’re prepared for the challenges ahead.
