Castelli Tri Short

What Our Gearhead® Experts Are Saying: “These are my go-to tri shorts because they stay put and disappear when I’m running. The KISS Tri pad is perfect—enough cushion for the bike but not bulky for the run. The SnapLock clip is a game changer for keeping your top from riding up during the bike leg, and the GIRO3 grippers keep everything secure without pinching.” We love the Castelli Tri Short for how effortlessly it transitions from swim to bike to run. The quick-drying fabric feels light and efficient as soon as we exit the water, providing a smooth fit that supports fast changes and steady pacing. The KISS Tri seat pad offers just the right amount of comfort on the bike, then virtually disappears once we start running—exactly what we want in a race-ready tri short.A hidden rear pocket gives us low-profile storage for gels or essentials, and the GIRO3 leg grippers keep the shorts locked in place without distraction. The SnapLock feature at the waist lets us clip in compatible tops to prevent ride-up during swim and bike legs, creating a streamlined, stay-put setup for every session. These shorts balance comfort, fit, and performance for both training days and full-send race efforts.
