Heat Cotton Pullover Men's Pajamas, Size M, V-neck? Features a chest pocket. - Color: Gray - Material: Smooth fabric and brushed fabric - Design: V-neck? - Pocket: Chest pocket - Pants: Open front, elastic cuffs with brushed fabric on the inside (see image) I purchased several of these about 3 years ago, but I'm selling them because I have too many pajamas. In my personal opinion, I found them to be very warm. While they may not be as warm as the popular medical device pajamas, they have a gentle, comforting warmth. This is just my personal experience. They cost 12,800 yen at the time of purchase (whether tax-inclusive or exclusive is unknown). (I found another one, so I will list it.) Thank you for looking.
