Women's 2026 Castelli Tri Short

The Women's Castelli Tri Short (2026 model, also known as TRI W SHORT) is a versatile, high-performance triathlon short designed for training, brick sessions, and racing across all distances—whether you're pairing it with a Castelli top for a two-piece race kit or using it standalone.

Crafted with quick-drying fabrics for fast transitions and minimal water retention, this tailored-fit short offers excellent muscle support and comfort. Key highlights include the proven KISS Tri seat pad, which provides reliable cushioning on the bike while staying virtually unnoticeable during the run; a SnapLock fastener at the waist to clip your top in place and prevent riding up during the swim and bike legs; GIRO3 leg grippers to keep everything securely in position without digging in; an inside drawcord for adjustable waist security; flat-lock stitching for chafe-free seams; and a hidden rear pocket perfect for gels, energy bars, a key, or credit card. With UPF 50+ protection and a lightweight feel (around 166g), it's ideal for warm conditions (15–40°C / 59–104°F) and delivers reliable performance from sprints to full Ironman distances.

Priced at $140, it strikes a great balance of pro-level features and everyday usability—making it a go-to for triathletes who value fit, functionality, and quick-dry speed.
