The Ridge Aspect Series Merino wool base layers were named the Best Thermal Underwear for men and women in a recent New York Times Wirecutter review.

Specifically, the editors called out the Aspect top's ability to go from city to trail, stating, "The Ridge Aspect Midweight Merino Wool Base Layer Long Sleeve crew is a technical shirt that doesn’t look too technical, and it has both a weight and a fit that make it appealing to wear by itself or under a layer."

Other details of the Merino wool shirt highlighted include the overall comfort, warmth and design elements such as the disappearing thumbholes, sleeve construction to eliminate chafing and UPF 50+ protection.

"Do you like exercising, hiking, or playing outdoors in the cooler months? How about working in the yard or going for walks? Do you do fieldwork, fish, or hunt? Go to sports practice or play in the snow? Chances are, there’s some outdoor activity you do in the winter months, and if so, a set of comfortable, functional base layers—lightweight pieces of clothing to wear under sweaters or jackets or pants—is a worthwhile investment." - New York Times, Wirecutter
