- JRJeanette R.Verified BuyerReviewingLong sleeve top — NATTWARM™I recommend this productMy sleep type I'm sometimes warm and sometimes coldRated 5 out of 5 stars14 seconds agoFan forever!
I purchased this top to go with the matching pants that I ordered. I was skeptical about wearing wool pajamas because I run warm most of the time. I was amazed at how comfortable these pajamas are and how much better my sleep is whilst wearing them. The top is lovely, not too tight and the ruffle on the hem is sweet. Love them!

nice and warm, but not so insulating that it gets hot. Can also be worn as a shirt under a blazer. The quality is top notch!
