Men's 2026 Castelli Tri Short
The Men's Castelli Tri Short (2026 model) is a high-performance triathlon bottom designed as a versatile, race-ready short for swim-bike-run transitions, ideal for pairing with Castelli tri tops in two-piece kits or for brick sessions and multi-discipline training.
This premium short delivers an excellent anatomic fit with quick-drying, lightweight fabrics that minimize water absorption during the swim and dry fast for the bike and run. It features the proven KISS Tri seat pad for reliable comfort over long bike legs without bulkiness on the run, an inside drawcord at the waist for a secure personalized fit, and the signature SnapLock fastener system to clip securely to compatible Castelli tri tops—preventing ride-up during aggressive movements. Additional highlights include compressive muscle support for reduced fatigue, flatlock stitching to avoid chafing, and a streamlined cut that performs across all distances from sprint to Ironman.
A mid-to-high-level choice for triathletes seeking pro-level functionality, durability, and seamless integration in Castelli's tri ecosystem—perfect for warm-weather racing or everyday training.
