As Wirecutter's top pick for the best thermal underwear, the Aspect Base Layer Long Sleeve Shirt is "a city-to-trail shirt" and their "most versatile pick." They capture what we love most about this base layer—it's incredibly versatile, incredibly comfortable and works well no matter where the day takes you. It feels great on your skin and keeps you warm, dry and comfortable, plus it has industry-leading durability. It's cut long to stay tucked in when skiing, and it has discreet thumb holes to keep your sleeves in place. Pair this shirt with the Aspect bottoms in full length or 3/4 length.
