Men’s White Thermal Underwear

Browse our men’s white thermal underwear for cosy base layers in crisp, bright shades. White thermal underwear is often the first thing people reach for when building a winter wardrobe, and for good reason. Within our men’s thermal underwear collection, white remains the most straightforward option to wear under everything. You’ll find varying heat and comfort levels, from light through to medium and maximum, thanks to our innovative Heatgen™ technology. Look out for supersoft seams and insulating brushed-back fabric for ultimate comfort when temperatures drop.

Your choice of fabric can make a big difference. Men’s cotton thermal underwear offers a soft, breathable feel that works well for everyday wear, while men’s merino-wool thermal underwear provides a finer, warmer layer that still feels light against the skin and has natural odour-resistant properties. Cotton and wool options come with added stretch so your undies stay comfy on active days. For your weekly rotation, look out for handy five-packs of crew-neck thermals that come with Cool & Fresh™ technology that helps you feel dry all day. StayNew™ finishes help white shades stay looking bright for longer.

If you prefer darker alternatives, men’s black thermal underwear offers a more defined look, while men’s grey thermal underwear sits somewhere in between. White, though, remains the easiest colour to wear under lighter clothing. For a full set, men’s long johns provide coverage through the lower half, while men’s white briefs or men’s white hipsters keep everything aligned underneath.
