Castelli’s Contatto jersey is surprisingly light given how thick it feels. The soft, fleecy inner is partly responsible for that impression as well as the jersey’s insulation.
You’ll be warm wearing it, and the only ventilation comes from the full-length zip. According to the stats, it wicks slightly better than similar weight jerseys – despite being a little heavier than some, it gained 161g during the ride and shed 53g in the hour afterwards.
But the picture is muddied by the fact that, although most of the inside of the jersey remains dry, the collar ends up damp.
Try combining the Contatto Jersey with the Nanoflex bib knickers for a good spring-weight combination.
