Product description
For a hike, ski day, or cold-weather commute, a merino base layer adds a comfortable layer beneath your outerwear. These men's long johns are made from 100% superfine merino wool, with three fabric weights to choose from for different layering needs.
The lightweight option is 165 g/m², the midweight is 250 g/m², and the heavyweight is 320 g/m². Choosing a weight lets you tailor the layer to your plans and the rest of your clothing.
Merino wool's moisture-wicking and odor-resistant properties support comfortable wear through outdoor activities and everyday routines. The fabric is 17.5 microns, and the pants are designed for softness and all-day comfort.

Everyday use
Wear the pants under hiking or ski clothing when you want a wool layer next to your skin, or use them as thermal pajamas on cold nights. Merino wool naturally wicks moisture and resists odor, useful qualities when a base layer is worn during active days or for extended everyday comfort. The midweight fabric is also described as naturally regulating body temperature for year-round comfort.
Compared with choosing a regular cotton layer, these pants offer merino wool's documented moisture-wicking and odor-resistant properties. The three weights provide a practical way to select a lighter layer for more flexible layering or a heavier fabric for a more substantial base layer. It makes sense if you want long underwear that can serve outdoor activities as well as daily wear, with a weight option suited to your layering preference.
What’s included
The heavyweight offering is described as 320 g/m² merino wool pants paired with wool hiking socks. The pants are the core of the product: a men's base layer intended for hiking, skiing, winter wear, and other uses where thermal underwear fits beneath everyday or outdoor clothing.
