Castelli Trasparente 4 Long-Sleeve Jersey - Men's
CastelliTrasparente 4 Long-Sleeve Jersey - Men's

Protection that blurs into the background.

Taking its name from the Italian word for transparent, the Castelli Men's Trasparente 4 Long-Sleeve Jersey blurs into the background on chilly training rides without the bulkiness of a protective riding jacket. The Trasparente 4 occupies the middle ground between jacket and jersey, making it a go-to choice for spring and autumn rides when a jacket is overkill, yet a regular jersey leaves you inadequately prepared for blustery conditions and oncoming showers.

It's constructed with Gore Windstopper X-Lite Plus along the front panel and sleeves, which provides full windproof protection and repels oncoming showers from soaking you to the core. By placing a windproof fabric along the leading edges, you'll remain insulated from chilly breezes when you're riding along at a brisk cadence. Castelli then places breathable thermal fabric along the back panel to exhaust built-up heat and reduce the jersey's likelihood of soaking up perspiration.

  • Minimalist feel of a jersey, wind-blocking protection of jacket

Great for cool weather

  • Familiarity: I've used it several times
  • Fit: Runs small
  • Size Bought: XXL

This is perfect for those cooler days from about 40-60F, and I’ve been wearing it during our variable “shoulder season” where a ride starts around 38F and finishes around 60F. Once I’m warmed up this jersey works great in the cooler end of that range, keeping things warm without trapping heat and moisture, and a couple inches of opening the collar and all’s well as the ride finishes and temps have climbed. I wear the Castilli “fishnet” undershirt under this jersey and its the perfect cool weather combo.

Like all things Castelli sizing runs small, but the 2XL was perfect for me

Really Good Fit

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: XXL

Bought the XXL. I’m 6ft, 208lbs and it fits perfect with a long sleeve base layer. Longer neckline is appreciated in windy conditions. Love the clutch front pocket. Enjoyable at 40-55 degrees on the East Coast!

Castelli style

  • Fit: True to size
  • Size Bought: Large

I purchased the lime green jersey for its high profile visibility. The garment has a high collar and the gore windstopper material is perfect for those cool windy will not be disappointed with this purchase.
