“You can’t stop night sweats.
But you can put an end to waking up soaked and shivering in wet pajamas.
Hot Mama and Wicking J. Sleepwear are made of a new lightweight polyester that absorbs moisture to help keep you drier.
GH staffers and patients at the center for menopause, hormonal disorders and women’s health at Columbia Presbyterian Eastside Medical Center, in New York City, each tested one brand for a week.
Result: “the pj’s eased the terrible chills associated with wearing wet clothing,” says Michelle P. Warren, M.D., the center’s director.
Independent lab tests also found that even after 20 washings, the fabric dried twice as fast as cotton.”

“The Good Housekeeping Institute tested two brands of sleepwear to help women who have night sweats, in which their clothing becomes soaked during the night, leading to shivering and difficulty sleeping, since women must get up to change clothes.
Sleepwear styles range from nightgowns to shortie sets for summer. The clothes are made from the same lightweight polyester fabrics used in active wear, which are known for their ability to wick away moisture from the body.
The tested products, which claim to wick away moisture, are: Sleepwear from Hot Mama (Hot Mama uses the fabric “Coolmax”). Sleepwear from Wicking J. Sleepwear: (Wicking J. uses the fabric “Intera”).
The institute’s textiles department evaluated the wicking of the sleepwear before and after 20 washes. An outside lab evaluated the drying time of the clothes and MVT (moisture vapor transmission), measuring the evaporative abilities of the fabric.
Results: The sleepwear wicked away moisture faster and better than regular fabrics, especially cotton, though Wicking J performed better than Hot Mama.
Even after 20 washings, both brands dried twice as fast as cotton.”
