Tri Short - Men's

What Our Gearhead® Experts Are Saying:

"These shorts make race day feel effortless. The KISS Tri pad is perfect—it provides comfort in the saddle but disappears on the run. The GIRO3 leg grippers keep everything in place without squeezing too tight, and the rear pocket is ideal for stashing a gel. Whether training or racing, these shorts are a solid choice for any distance."

From swim to bike to run, we need gear that adapts as quickly as we do. The Castelli Tri Shorts are built for all-distance triathlons, combining a streamlined fit with a race-ready design. The KISS Tri seat pad offers just enough cushioning for comfort in the saddle while staying low-profile for the run.

A secure rear pocket holds gels or energy bars for mid-race fueling, and the GIRO3 leg grippers keep the shorts locked in place without restricting movement. The UPF 50+ rating provides protection under the sun, while flat-lock stitching ensures chafe-free comfort. Whether tackling a sprint tri or pushing through an Ironman, these shorts deliver the performance we need.
