Chill Angel

When cancer treatment chemotherapy resulted in her own struggle with relentless, internal body heat, Betsy Seabert, a performance outdoor clothing technology leader, conceived Chill Angel. The innovative line of sleepwear is made from 100%, super-fine merino wool, and was inspired by her own experiences with sleep deprivation and the hot flashes of women around her.

While not technological, Chill Angel's Temperature Balancing Sleepwear does represent a new concept in cooling sleep solutions. Its super soft pieces use wool's natural moisture wicking to keep you cool and dry from day to night. The entire line is made from buttery soft, 150-gram fabric with an ultra-fine low micron count of 16. In other words, it's a soothing, itch-free material that will regulate your temperature while you snooze.

The Essential Tank Long is one of the Chill Angel's most versatile pieces, and can be worn through a yoga workout, everyday activities, and, of course, sleep.

With no break in the heat on the horizon, these are the long-awaited advances in women's clothing we've been waiting for: cool comfort, developed with a woman's rising body temperature in mind. Here's to innovation and the dedication of brands (many of which were founded and run by women!) who continue to beat the heat in all the coolest ways.
