Ideal for indoor wear to stay warm on cold winter nights or for outdoor activities such as hiking or skiing, women's thermal underwear sets will keep you comfortable.
Women's thermal underwear sets come in different materials
Keep your body warm in the cooler weather with a range of women's thermal underwear sets. Choose from a variety of materials including cotton, polyester, and micro-fleece to ensure you have the right underwear for every season.
Cotton is a natural fiber that's gentle on the skin and doesn't cause irritation. Breathable and lightweight, cotton thermals are perfect for those in-between seasons where you need an extra layer. Cotton is machine washable and colorfast so your thermals won't fade over time, allowing you to enjoy funky patterns or bold colors.
Polyester is a long-lasting, synthetic fabric, which makes it an ideal summer or winter base layer. Being durable, polyester thermals are essential for high-intensity activities such as running, hiking, skiing, or snowboarding. Thermals are lightweight and wick moisture from the skin to keep you dry and warm.
Microfiber thermals are tighter fitting and contour to your body shape to give you a comfortable fit. Microfiber also keeps its shape well to ensure no baggy, loose areas. Choose microfiber blends including spandex for compression-style underwear that offer extra support for sports or winter activities. Fleece-lined microfiber thermals make a great layer for winter hiking or for sleeping in on cold winter mornings.
