"Dagsmejan offers a luxurious sleepwear experience that prioritizes comfort and quality- exactly what you need for sleep. The fabric is soft and very breathable with moisture-wicking properties so important for women having hormonal fluctuations. I wear tops and bottoms that work well for sleeping and transitioning to comfy loungewear for a lazy Saturday morning. It's a five-star experience!" — Dr. Wells, Sleep and obesity medicine physician and founder of Super Sleep MD.

- JRJeanette R.Verified BuyerReviewingPants cuff — NATTWARM™I recommend this productMy sleep type I'm sometimes warm and sometimes coldRated 5 out of 5 stars13 seconds agoAbsolute comfort!
I was skeptical about buying woolen pajamas because I always am “hot”, but these pants are amazing! They have pockets ( I’m a fan). They fit well and are not too tight and they have given me some of the best nights of sleep I have ever had! They are soft and comfortable, not at all itchy or scratchy and fit me quite well. I am now your newest fan!

I just bought these pajamas after owning 2 gowns for 2 years and I won't sleep in anything else, that's how comfortable they are. Soft, stretchy, perfect fit even for a shorter person. No more cold shoulders at 3:00am and now sleep through the night. The pajamas and gowns are ideal for anyone who likes to be cosy!
