Women's Thermal Underwear

Winter is coming, and the last thing you want is to be left out in the cold. Make sure you’re fully prepared for this winter season with XTM’s thermal base layers.  This season we’ve got a great range of winter gear for you to browse through, but you should always start with your base layers. As the layer closest to your core, thermal wear must be of the highest quality and made with ultra-comfortable fabric. And for this reason, we’ve created snow thermals that are prepared to go out and tackle the cold with you. Put these on as an extra layer and instantly notice the difference.

Our women’s thermal wear fits 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 crop tops.  Your new thermal wear will slide right underneath a pair of our women's snow pants and provide extra warmth that you can feel. We’ve also got thermal wear for men, too. So, be sure to share and shop through our men's thermal wear range as well.

Frequently Asked Questions

Should I 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.
