When there's a chill in the air, many boys struggle to stay warm. However, as most parents know, that will never stop them from going outside to play in the snow! Give them the protection they need to have fun in the great outdoors with boys' thermal underwear from Lands' End.
Think of our thermals as a boys' base layer for their favourite winter outfits. They're designed to sit close to the skin, insulating their bodies against cold air and preventing heat loss. We make our boys' thermals from polyester with a dash of elastane for the stretch he needs when he's on the move. This material will keep him toasty warm without adding bulk to his outfits.
You can layer any apparel items you want over a boy's thermal set including boys' hoodies, sweaters, denim jeans for boys, or trousers. Add a coat and knit hat and he'll conquer the coldest of days. Boys' thermal long underwear also makes a great alternative to boys’ pyjamas during the colder months.
We sell boys' long johns and thermal undershirts separately and paired as sets for your convenience. They're ideal for active boys as their fabric does more than insulate. It also wicks moisture away from the skin, ensuring he doesn't feel sweaty when he's enjoying snowball fights or sledging. That should also keep odours at bay so he can play longer with confidence.
Our boys' long underwear is available in a variety of colours and prints. Choose basic blue or black or enjoy the whimsical appeal of stripes, camouflage print, Fair Isle stripes and more. The choice is yours when you shop at Lands' End.
Visit Lands' End for long underwear for boys of all ages. We have boys' thermal wear for toddlers, little boys, and big boys too. No matter their size, stretchy elastane-enhanced fabrics and elastic waistbands help you get the perfect fit every time you shop with us at Lands' End.
