The Glacier long sleeved men's base layer has been specifically developed for winter use. Through the application of various knitting techniques at strategic areas, a technique known as 'body mapping,' the Glacier optimally balances insulation with ventilation. A dense knitting structure maximizes insulation where necessary, which is crucial for comfortable winter riding. Meanwhile, moisture management is enhanced at other locations, including under the arms. This helps transport perspiration to the outside of the garment, where it spreads over a wider surface and evaporates more quickly. The result is a base layer shirt that keeps you dry and warm.
