Castelli Espresso 2 Jersey Review 2026

What Is the Castelli Espresso 2 Jersey?

The Espresso 2 is Castelli’s refresh of its best-selling all-day comfort jersey, built for long training rides rather than racing. It’s designed to be comfortable for hours in the saddle without being restrictive — a useful rotation piece alongside a race-fit jersey for triathletes who spend most of their bike volume on long, steady rides.

Verified Specs

• Fabric: Castelli’s Air_O Stretch, an Italian-made fabric with high horizontal stretch for comfort and limited vertical stretch to keep the back pockets supportive (92% polyester / 8% elastane)
• Pockets: Three open rear pockets plus a fourth zippered security pocket for valuables
• Zip: Full-length YKK Vislon zipper with an easy-grip pull
• Fit details: Raw-cut sleeve endings, silicone-gripped elastic waist hem, UPF 30 sun protection
• Price: £84 (short sleeve) / £99.99 (long sleeve) at Tredz, both currently in stock

Who Is It For?

This is a training jersey, not a race-day aero piece — Castelli itself positions the Espresso range for all-day wear rather than crit racing. For triathletes, it’s a sensible pick for long steady rides, bike-leg brick sessions and winter base miles where a relaxed, breathable fit matters more than aerodynamics. If you want a tighter, faster cut for racing, look at Castelli’s Free Aero or Aero Race lines instead.

Buying Tips

• Choose long sleeve for cooler shoulder-season training, short sleeve for summer base miles — both share the same Air_O fabric and pocket layout.
• The relaxed fit runs closer to true size than Castelli’s race-cut jerseys — if you normally size down for Castelli’s Aero Race range, stick with your regular size here.
• Use the zippered security pocket for a card or key on unsupported long rides rather than stuffing valuables into the open rear pockets.
