There isn't anything better than a merino wool pajama, when it comes to staying cozy warm on a chilly winter night. Our NATTWARM™ collection is four times more breathable than regular wool and on top of that 50% lighter. TRAVEL + LEISURE recommends our NATTWARM™ pajama long set for women primarily because of its warm yet lightweight properties. The stylish long sleeve top with over-thumb sleeves, combined with the matching trousers with the soft cuffs at the ankle, let you easily run to a short coffee appointment without anyone noticing that you are actually wearing a pajama.
