Men’s Cotton Thermal Underwear

Our men’s cotton thermal underwear combines an extra layer beneath your clothes with a gentle, breathable feel on your skin. Look out for our Heatgen™ technology for cosy warmth with a soft finish. When it comes to colourways, our men’s thermal underwear in fresh white or soft cream is an ideal option to wear under light-coloured outfits. To team with darker colours, we have men’s thermal underwear in black, plus modern grey and rich blue.

Shop our main collection of men’s thermal underwear for a selection of materials to suit your preference. For matchless protection on the chilliest days, you can pick from our assortment of men’s wool thermal underwear. You’ll also find men’s merino wool thermal underwear for effective warmth with a luxuriously soft feel. Choose from our thermal vests and T-shirts for targeted insulation around your core. If the conditions call for all-over coverage, go for a long-sleeved top, and team it with a pair of men’s thermal long johns.

When it’s time to upgrade your undies selection, our collection of men’s cotton underwear has you covered. We have jersey trunks and hipsters for a smooth, flexible feel with plenty of coverage, and men’s cotton boxers for a looser, more relaxed shape. If you like a neat and supportive style, have a look at our men’s cotton briefs and slips. Keep an eye out for pairs with our Cool & Fresh™ technology that delivers lasting hygiene and freshness, and stock up on your favourites with our handy multi-packs.
