The Best Cooling Pajamas for Comfy Nights When the Weather Gets Hot

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links."

Summer is coming, and bringing with it uncomfortably hot nights in some parts of the country — so hot that air conditioners, ceiling fans, window units, and open windows struggle to keep up with the intensity. And hot weather isn’t the only trigger for warm nights, either: menopause, medications, and even stress and anxiety can cause sweaty sleeping conditions that are uncomfortable and unpleasant any time of year.

Pajamas with cooling properties can help. The best cooling pajamas are typically made from natural materials, such as cotton, bamboo, linen, or silk. They’re loose fitting, breathable, and have moisture-wicking properties. And our picks for the top cooling pajamas are just plain cute, too, in styles including two-piece sets, shorts, capri pants, joggers, tanks, sleep shirts, nightgowns, and more.

No matter your budget, there's something just for you on our list.

These are the best cooling pajamas to keep you comfortable and dry on hot nights (or for hot sleepers).

What to look for when shopping for cooling pajamas

✔️ Natural materials: If you're in the market for cooling pajamas, it's important to select breathable fabrics like cotton, bamboo, linen, eucalyptus, and silk. “Avoid synthetic materials such as polyester or nylon, which can trap heat and moisture,” advises celebrity wardrobe stylist Pilar Scratch.

✔️ Moisture-wicking: Scour product descriptions and reviews in search of moisture-wicking properties, features that promote airflow, and other temperature-regulating features. “Look out for features like moisture-wicking and ventilation to help regulate your body temperature and ensure a comfortable night's sleep,” Scratch says.

✔️ Breathability: Stephen Light is a certified sleep science coach and the CEO and co-owner of Nolah Technologies, where he’s involved in product development, including cooling bedding. He underscores breathability for keeping cool at night. “Breathable pajamas allow body heat to escape and fresh air to flow in,” he says. “Meanwhile, fabrics that wick moisture assist your body's natural cooling system by wicking away sweat for quick, cooling evaporation."
