What Our Gearhead(R) Experts Are Saying: "This jersey is my go-to for 50-degree starts and long tempo rides. The dual knit fabric feels super smooth against the skin but breathes better than anything I've worn in this weight. It layers well under a vest and stays put no matter how hard I ride."When the forecast sits just above chilly but far from warm, we reach for the updated ONE Long Sleeve Jersey. Designed with a refined fit and premium dual-knit construction, this jersey hits the balance of warmth and breathability we need on shoulder-season rides. The fabric feels soft and weightless, but its coverage is dialed for early spring spins, cool autumn rollers, and even long base miles when the sun's out but the temps lag behind. This evolution of the Signature Bio Long-Sleeve Jersey features a bio-based material blend and an improved silhouette with more precise detailing. It fits like a second skin but allows airflow and layering flexibility-ideal for that tricky 45-60degF window. From solo road loops to long gravel routes, this jersey works as hard as we do.
