Sweatssleep

Sweatssleep is a brand and product line that focuses on personal climate control to improve sleep. It offers a range of products—including sleepwear, bedding, and accessories—designed to regulate body temperature and reduce night sweats. Central to Sweatssleep’s approach is the use of moisture-wicking fabrics and layer materials that incorporate phase-change materials to help maintain a stable skin temperature during the night.

Established in 2018 by a group of textile engineers and sleep scientists, Sweatssleep began with cooling pillowcases and sheets and later expanded into pajama sets and mattress toppers. The company also developed a companion app that collects data on ambient conditions and provides sleeping recommendations, though the core product remains physical textiles and bedding rather than software.

Products are marketed to hot sleepers, individuals experiencing night sweats from hormonal changes, athletes in recovery, and people living in warm climates. The line emphasizes breathability, moisture management, and the ability to adapt to different sleep environments through passive materials rather than active cooling alone.

Reception is mixed in reviews: users report improved comfort and reduced nocturnal sweating for some, while others cite high price points or questions about long-term durability. Sweatssleep competes with other temperature-regulated bedding and sleepwear brands in a growing market for sleep technology.
