Polar Base Layer Crew
new
Color: Onyx Black
The Polar Base Layer Crew is a high-performance garment providing substantial warmth without limiting range of movement.
Technical Features
Better Fabric For A Better Base Layer
Crafted using flat lock seams to enhance comfort and eliminate chafing, this crew top is composed of 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. Rounding out this crewneck base layer is a back yoke with a center-back seam.
Proven Cut & Shape, All-New Fabric
This base layer sports a slight drop tail hem, along with double-layer cuffs with reinforced thumbholes that make for super easy layering or a seamless connection beneath a pair of gloves. Our Polar Crew Base Layers harness the proven shape, cut, and silhouette from AETHER’s existing Premium Merino Base Layers, while receiving a more advanced construction.

Built For Whatever Winter Has In Store
Though primarily intended for use on the slopes, this style also makes for an exceptional base layer for cold-weather motorcycle riding. Made in America, the Polar Base Layer Crew is designed to pair with our Polar Base Layer Pant.
