Men's Thermal Pants

Pull on a pair of men's thermal or heated pants, and you're already ahead of the cold. Our range of insulated base layers and underwear pants is built for everything from a Canadian commute to a full day outdoors. Fleece-lined thermal pants are the go-to when temperatures really drop. The interior lining traps heat close to your body, making them ideal for outdoor work or extended time in unheated spaces. If you want something that moves more freely under work pants, cotton thermal pants are a lighter pick. They sit close to the skin without bulk and hold up well through repeated wear and wash.

For full coverage that tucks neatly beneath outerwear, thermal long johns are perfect. Fitted through the leg with a smooth exterior, they disappear under any bottom layer without bunching or shifting. If you want warmth in the fabric, pick merino wool base layer pants. Merino wool regulates temperature well and handles moisture naturally, which makes it a reliable choice when your activity level changes throughout the day. If you're physically active in the cold, moisture-wicking thermals will move sweat away from the skin so you're not sitting in a damp layer. Microfiber thermal underwear rounds out the range for anyone who wants a smooth, lightweight option that still delivers warmth.
