    Very Comfortable Sleep Wear

    I have several pieces of sleep wear from Dagsmejan including Nattwarm short and long sleeve tops and long pants. They fit like an outer skin. The wool blend fabric is very comfortable and does keep me warm on very cold nights. The difference pieces are also very reasonably priced compared to other top brands. I highly recommend Dagmejan. I order XL in the bottoms and XXL in the tops.
