What's the Most Breathable Fabric for Thermals?

Thermal sets for women have become a staple of many people's wardrobe. They keep you warm, cozy, and, most of all, dry with their moisture-wicking abilities. Whether you're trying to stay cool in the heat or warm in the winter, you need a breathable fabric that will help keep the sweat from your body. From the refreshing touch of the cold mountain air in the summer to the chilly breath of the winter season, an excellent breathable fabric is essential for your comfort.

Factors to Consider:

1. The weight and construction of the fabric matters. A piece of lightweight fabric is perfect, as it won't weigh you down. Even if it's a snug-fitting set of women’s long johns, the thinner material will still do its job when releasing the sweat into the open air. If you can hold the fabric up to a light source and see a lot of the light, then that fabric is breathable. It's not the most scientific test to do, but it still works.

2. Moisture-wicking is an essential part of the material. If the fabric wicks away excess sweat, then the chances of it being a breathable fabric are excellent. Both go hand-in-hand, but some fabrics are better than others when it comes to these features.

3. The fit of the fabric also affects the breathability. The material no longer has to be loose-fitting. New technology has made tight-fitting thermals as breathable, if not more, than traditional fitting clothes. You want the fabric to be close to the skin, but it is not so tight that it fills like you can't breathe. It should feel like a second skin.

Fabrics to Consider:

1. Polyester is a widely used material when it comes to breathability and moisture-wicking. It is a standard fabric used in the fitness industry and is also used in thermal sets for women. It wicks away moisture and dries quickly as the material is made to be breathable. It is also cost-effective and durable, making buying clothing like women’s long johns easier on the pocketbook.

2. Silk is relatively famous and is a breathable fabric. Still, it isn't as durable as polyester and can cost a bit more. It's a luxurious fabric that is lightweight. It's great for summer, but it may not be worth the purchase due to its cost.

3. Merino wool is another gold standard in the industry. It's soft and breathes well, which gives it excellent moisture-wicking features. It's not as durable as polyester, so if you wear your thermals for any sports-like activities, then wool may not be your first choice.

Out of these three considered, polyester or even a polyester blend will be the perfect choice for breathability. The cost of polyester makes it an attractive option. This is especially true if more than one pair is needed. With winter coming or already here, a few pairs of thermals will serve you well this season.
