  • Men's Stretch Thermaskin Long Underwear Mock Neck Base Layer

    Men's Stretch Thermaskin Long Underwear Mock Neck 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.

  • Men's Tall Silk Interlock Crew

    Men's Tall Silk Interlock Crew

    Silk is lightweight and one of nature’s best insulators. So this crew is great for layering under sweaters, shirts, flannels, you name it. It also wicks perspiration away from your skin, helping maintain your body’s heat, which is crucial for comfort in cold weather.

  • Men's Comfort First Stretch Knit Crewneck T-Shirt

    Men's Comfort First Stretch Knit Crewneck T-Shirt

    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.
