He Loves It! Me Too!

Bought a sleep shirt and shorts for the hubby as he sleeps very hot, waking several times during the night, throwing off covers, tossing, turning and waking me up several times during the night! And, honestly, that behavior has practically stopped! He loves these sleeping garments! And, so do I! Saw this product advertised in Better Homes and Garden and decided to try them, even though they are very expensive! Well worth the money for a good night sleep!

Brilliant shorts

Most of the shorts I have had to sleep in always make me too hot and itchy. These are super cool and comfortable. I wish they would make boxer shorts to wear during the day!!
