Lands' End Thermal Base Layer Long Underwear Thermaskin Pants - Boys'

The first frost on the grass is just an invitation to head outside, not a signal to retreat indoors. Built with Thermaskin technology, these Lands' End base layer pants act as a second skin that traps core heat while actively whisking away moisture during high-energy backyard expeditions or long afternoons on the sledding hill. The fabric is remarkably thin, slipping easily under snow pants or jeans without ever feeling restrictive, ensuring movement remains fluid from the first run to the final tumble. We’ve used flatlock seams throughout the construction to eliminate those irritating friction points that usually cut a day short, meaning total focus stays on the task at hand—whether that’s building the perfect snow fort or mastering a new turn on the slopes. By maintaining a steady microclimate against the skin, this layer does the heavy lifting so the chill of a biting wind never stands in the way of a long day of discovery.
