Jimmy Youngwrote a review of Castelli Fondo Full-Zip Long-Sleeve Jersey - Men's on March 24, 2018
Familiarity: I've used it once or twice and have initial impressions
Warm and comfortable. I'm built more like a football player than a cyclist but the XXL fit great. Arms slightly tight but better tight than baggy where it flops around in the wind. Rode when it was in the 40's and once in the low 50's. Worked well in both conditions. I just used different types of base layers for the different temperatures.
