Stay Warm in Winter With Smitten’s Merino Wool Thermal Underwear for Men

Our thermal underwear is made of 100% superfine merino wool. This is a great material for layering and wearing beneath garments, as it's super breathable and adjusts with the weather. When it’s cold, you can stay warm with the wool thermal underwear beneath your long johns, pants, tops or jumpers.

Smitten’s thermal underwear and base layers are particularly great during the cooler parts of the year, particularly for those who enjoy getting outdoors, mountain biking or hiking. Being layered up helps you stay comfortable, no matter what the weather throws at you. Merino wool provides an unbeatable skin feel.

What Makes Merino Wool The Best Material for Thermal Underwear? 

Merino wool is unique, with properties unlike any other textile, making it ideal for men's thermal underwear and socks.

Merino wool is:

  • Temperature regulating
  • Odour resistant
  • Naturally insulating
  • Absorbent

Even in a thin layer, when you wear your thermal underwear, you’re provided with excellent protection and comfort. Maximise your comfort in luxurious merino wool.
 

The Most Comfortable Thermal Socks

Keeping your feet cosy and warm on cool days is a small luxury everyone should enjoy. Our thermal socks are designed for ultimate comfort and warmth, without getting sweaty. That's thanks to the unique properties of merino wool which traps heat when you are cold, but lets it out to prevent overheating and sweating.

Sustainable & Ethical Men’s Thermal Underwear

All of our thermal socks and underwear are made of ethically sourced merino wool. Caring for the planet is one of our core values, which is why we aim to be sustainable at every step of the production chain. We use merino wool sourced from Australian farmers and only take the wool of non-mulesed sheep. Your thermal underwear is sent in biodegradable packaging that can even be composted!
