10 Best Thermals For Winter 2025 in the United States

The Cuddl Duds Thermal Underwear for Women is designed for cold-weather comfort, featuring a fleece-lined interior for warmth and a soft exterior for comfort. The material blend of 93% polyester and 7% spandex ensures a snug fit with a bit of stretch, making it comfortable for everyday activities. The set includes both a top and leggings, making it a complete base layer option for winter. The moisture-wicking fabric helps manage sweat, keeping you dry throughout the day.

Additionally, the garment offers 50+ UV protection, adding an extra layer of defense against the sun's rays, and includes thoughtful design features like thumbhole sleeves and a tag-free label for enhanced comfort. The heavyweight nature of the fabric might be too warm for milder winter days, and the snug fit might not suit everyone's preference.

Its sleek design makes it versatile enough to be worn alone or layered under other clothing. Ideal for those who need reliable warmth and comfort in cold weather while enjoying outdoor activities or simply lounging at home.

The G Gradual Women's Fleece Lined Joggers are designed for cold weather, making them suitable for winter activities like running, hiking, or walking your dog. The thermal fabric with a warm fleece lining ensures you stay cozy in temperatures below 30°F. The material, made of 77% polyester and 23% spandex, strikes a balance between flexibility and warmth. The high waistband with a 4-inch rise and adjustable drawcord offers excellent tummy control and a customizable fit, which adds to your comfort without feeling bulky.

One significant advantage is the water-resistant coating, which helps keep you dry in light rain or snow—ideal for outdoor activities. Additionally, these joggers resist pet hair, which is a plus for pet owners. With two zipper pockets, you have a secure place to store your phone and other valuables, freeing up your hands when you're on the move.

While the joggers are versatile and can be used for various activities, they may not be the best option for very intense workouts due to limited moisture-wicking properties, as thermal fabrics typically prioritize warmth over breathability. Also, the layering compatibility might be restricted; the snug fit and fleece lining could make layering with other thermal gear challenging. Machine washing is convenient for maintenance, but gentle cycles are recommended to preserve the fabric quality. These joggers are a solid choice for anyone looking for warm, comfortable, and water-resistant options for casual winter activities.

While the leggings are designed to be durable, frequent machine washing might affect their longevity.
