What Our Gearhead(R) Experts Are Saying:"The Pisa Thermal is my go-to on those crisp mornings when it's too chilly for a summer jersey but not cold enough for a jacket. The fleece interior feels warm against the skin, while the fit stays snug without restricting movement. I really like how the cuffs tuck under gloves without bunching, and the longer drop tail keeps everything covered in the drops."When temperatures drop but the roads stay dry, the Castelli Pisa Thermal Jersey gives us the balance of warmth and breathability we need. Its fleece-backed Lycra fabric keeps the chill off without overheating, making it ideal for shoulder-season miles or long winter base rides when paired with a baselayer. The slim wrist cuffs slide neatly under gloves, and the elastic waist with gripper hem ensures the jersey stays in place as we shift through riding positions. A full-length zipper with neck cuff makes ventilation easy without snagging, while the drop tail maintains coverage even when we're stretched low on the bars. With three rear pockets to stash nutrition and essentials, the Pisa Thermal brings together performance and practicality in one versatile piece.
