Description

You can't go wrong with Wirecutter's top pick for the best thermal underwear. Our Aspect Base Layer Long Sleeve Shirt is a "city-to-trail shirt" and Wirecutter's "most versatile pick." They capture what we really love about this base layer top—it's endlessly versatile and the perfect companion no matter where the day takes you. It's soft and cozy against your skin and it keeps you warm, dry and comfortable. Plus it features industry-leading durability thanks to our (m)Force Technology. It has a slightly longer cut so it stays tucked in when skiing or snowboarding, and it has discreet thumb holes. Pair it with our Aspect High Rise Bottoms.

"It's a versatile layer that handled the transition well from walking around in 30-degree-Fahrenheit temperatures to a hot and crowded house party.” - WIRED Magazine
