The Polar Baselayer Crew sports thumbholes at the cuffs, allowing the garment to be used to achieve a seamless connection under a pair of gloves, though they can also be bypassed for a more relaxed fit.
















Built for optimal comfort and mobility, the Polar Baselayer Crew is a high-performance take on traditional thermals, benefitting from an advanced proprietary construction and a bevy of small but game-changing design details that collectively result in a superior baselayer.

Better Fabric For A Better Baselayer
The Polar Baselayer Crew is cut from Polartec® Power Grid™ Fabric — a proprietary breathable, lightweight fleece with multi-way stretch, moisture-wicking, and thermoregulating properties. The construction’s waffle pattern also helps to further bolster warmth and heat retention.
