#GIRO109 Competizione 4 Short-Sleeve Jersey - Men's

What Our Gearhead® Experts Are Saying:

"I like this as a go-to jersey for everything from training rides to faster group efforts. It’s got a nice balance—not too tight but still performance-oriented. The stretch fabric moves well, and the raw-cut sleeves feel smooth without any restriction."

We reach for the GIRO109 Competizione 4 Short-Sleeve Jersey when the ride could go anywhere—from steady training miles to fast-paced group efforts. Castelli designed it to strike that perfect balance between comfort and performance, so we feel just as good spinning easy as we do pushing the pace.

The all-over stretch fabric creates an ergonomic fit that adapts to our movement on the bike, while raw-cut sleeves deliver a clean, modern feel without pressure. A full-length YKK® Vislon® zipper makes ventilation adjustments quick and easy, and the silicone waist gripper keeps everything securely in place. With spacious rear pockets for ride essentials, this jersey is built to handle everything from daily spins to race-day efforts.
