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.
