Merino Seamless Base Layer

Castelli Merino Seamless Base Layer Utilising the natural warmth and moisture management properties of merino wool, the Castelli Merino Seamless Base Layer offers unrivalled comfort for cycling during the cooler months of the year. Whether rides are long and steady or short and intense, the base layer regulates temperature and, thanks to anti-bacterial performance, maintains freshness. A seamless construction ensures there's no distracting irritation, and the low collar works easily with any style of jersey or jacket.
