Description
Warm, insulating, comfortable and durable, the Castelli Flanders Warm Long Sleeve Base Layer uses a SottoZero Fleece multi-denier, lightweight, 100% polyester fabric. Comfort is provided by flat-lock stitching and a flat hem that is long enough to be tucked into the shorts or tights. A mesh construction under the armpits improves breathability and the grey design with signature Castelli graphics looks great whatever you are wearing over it.
A base layer for the coldest of winter days. With a temperature range of between -5° and 8°C you are sure to stay comfortable and warm no matter the conditions. Simple yet effective, drying fast, wicking moisture away. This is the ideal undergarment to be worn under just a single jersey or jacket depending on the temperature.
