The Winter Long Sleeve Base Layer is designed to keep your core warm on the coldest days. Sitting next to skin and worn under your jacket as part of a layering system, the Winter base uses Polartec® Alpha™ on the interior layer and Polartec® Powergrid™ Fleece on the exterior to offer the best thermal protection.
Ergonomically designed to sit close to skin, with a lightweight, low bulk construction the combination of Polartec® fabrics ensure warmth is maintained when temperatures dip into negative numbers while keeping bulk to a minimum.
Polartec® Alpha™ was developed for the U.S. special forces to regulate comfort in changing conditions. Requiring consistent warmth and breathability in extreme temperature variations without the need to remove layers. These qualities are closely aligned to those of a cyclist in the colder months.
Polartec® Powergrid™ is a patented grid construction knit that increases warmth and breathability, while also reducing fabric mass.
"In deep winter having a base layer that reacts to a wide range of temperatures is key, regulating your temperature to keep you on the limit. The addition of Polartec fabrics means not only does this base deliver warmth, it does it with minimal bulk."
