Base Layers & Men's Best Boxers

Men's Monogrammed Underwear, Cotton Undershirts & Thermal Underwear

Our men's long underwear provides warmth you can count on from cold winter work commutes to bedtime when the furnace hasn't kicked in yet. With our base layers, you'll experience warmth without overheating your body, thanks to our innovative fabrics designed to move perspiration away from your skin, helping to maintain your body’s microclimate of heat. Our best boxers and other men's underwear keep you cozy while you're walking the dog on a rainy morning and shoveling fresh snow from the sidewalk. Our cotton undershirts and other vital base layers are available in regular and tall sizes, and consider adding a monogram for a personal touch.

You'll reach for our men's long underwear when the driveway and sidewalk need shoveling, and you need extra warmth. Our base layers quickly wick moisture away from your body.

  • Men's Tall Comfort-First Crewneck Undershirt

    Men's Tall Comfort-First Crewneck Undershirt

    We had a few lucky folks test out these new undershirts here at Lands’ End® headquarters. The consensus? There’s no better tee to wear as an undershirt. The smooth, comfortable fabric resists chafing, and the wicking helps manage moisture to stop perspiration before it starts. On top of that, the stretch had a few surprising benefits: not only is it more comfortable, but thanks to the added give, it’s easier to keep tucked (since it stretches rather than pulls when you bend over or reach up). Naturally, all that comfort makes it a great choice for lounging or sleeping, too.

  • Men's Silk Long Underwear Turtleneck

    Men's Silk Long Underwear Turtleneck

    This great fabric makes them perfect under sweaters, flannels, you name it. Silk is light, layerable and one of nature’s best insulators. It’s also very breathable, so you won’t overheat once you step inside. Lands’ End® silk is made with an interlock knit, so it’s up to 30% denser, warmer than ordinary jersey knits. This Turtleneck has long sleeves and tails long enough to stay tucked in.

  • Men's Stretch Thermaskin Long Underwear Quarter Zip Base Layer

    Men's Stretch Thermaskin Long Underwear Quarter Zip Base Layer

    If there’s one thing we’ve learned from Wisconsin winters, it’s that you don’t skip your base layer. That extra bit of warmth can be the difference between feeling mildly annoyed by the cold ... and feeling like you just got hit by an ice-nado. More than just feeling warm, though, we want you to be comfortable. So we developed a fabric that’s significantly stretchier than the stuff we’ve offered in the past. The extra give provides a more natural, flexible feel that makes it virtually disappear. And since the last thing you want to be is damp when it’s cold, Thermaskin™ technology pulls moisture away from your skin to keep you comfortably dry, too. This is one base layer you don’t want to skip.
