All HARALEE clothing and pillowcases are made of moisture Wicking fabrics. These fabrics draw perspiration away from the body to the fabric where it evaporates quickly. This means you are not wet, cold, or uncomfortable, and you can continue to stay comfortable while sweating day and night. So if you are perimenopausal, menopausal, postmenopausal, or just have a high internal thermostat, we have something for you to stay comfortable, dry and cool. Because I want to do more than pray for a cure for breast cancer, a portion of every sale is donated for this cause. Join me in Staying cool, but looking hot with our sleepwear of Wicking pajamas, night sweats pajamas, nightgowns, and all that help with menopause symptoms.
