Men's Thermal Underwear

We’ve got a great range of outdoor gear for you to browse through, but you should always start with premium undergarments. As the layer closest to your core, thermal layers must deliver on performance and be ultra-comfortable. And for this reason, we’ve created snow thermals that are prepared to go out and tackle the cold with you.

Our men’s thermal layers fit perfectly under all your layers to keep heat in and moisture out. Thermal base layers can be purchased individually or as sets. Choose from tops, bottoms, and even boxer briefs. Your new thermal underwear will slide right underneath a pair of our men’s snow pants and provide extra warmth that you can feel. We’ve also got thermal layers for women, too. Be sure to share and shop our women’s thermal layers range as well.

Frequently Asked Questions

Do you wear underwear under thermals?

Wearing underwear under your thermals really comes down to personal preferences. However, if you’re comfortable going commando just keep in mind that without a barrier between your skin and thermals, it may mean increased moisture and odour. You can mitigate this by opting for Merino thermals which are anti-microbial, moisture-wicking and odour-resistant.

How tight should thermal underwear be?

Your thermal underwear should be snug, but not overly tight so that it restricts movements. Comfort is key. Since the purpose of thermals is to provide an extra layer of insulation, a snug fit will help trap your body heat to keep you warmer for longer.
