If your choice of pajamas isn't keeping you warm throughout the night, it might be time for a thermal set. Thermal loungewear is not only ultra-soft, but it's also designed to trap the heat your body naturally gives off. And while there are plenty of suitable options available at your fingertips, one affordable set in particular has gotten tons of rave reviews from Amazon shoppers. 

Made from a spandex and polyester blend, the Thermajane Thermal Underwear is breathable and wicks away sweat as it keeps you warm. The fabric features a four-way stretch, so you can comfortably move about without feeling constricted. And since the lightweight material hugs your body, you can easily layer on additional clothing if you need it. The fleece lining adds an extra element of coziness to the snug set. 

The number one Amazon best-seller for thermal underwear, the popular set has racked up over 7,000 five-star ratings from shoppers who claim they are "silky smooth" and "very stretchable." Others say the thermal pajamas fit extremely well regardless of whether you're tall or petite.

"These are very SOFT, super stretchy, warm and comfortable," wrote one shopper. "I liked them so much I ordered another pair, and will order even more. They are made with a material that doesn't bind up with other fabrics. If you need something for layers under riding gear these are AWESOME. I also liked how long they are — I'm tall and it's hard to find something that is long in the arms, legs and body!"

The best-selling thermal set comes in 12 different shades, including neutrals and bright colors. Have your pick from sizes XXS to 3XL — prices for all stay under $26.
