Should You Wear Undies Under Thermal Underwear?

If you're wearing thermals for winter, you may be wondering if it's a good idea to wear underwear underneath. Wearing underwear will not decrease the thermal insulation provided by thermals, but it will provide comfort and support. It's also socially acceptable and safe, as thermals act as a barrier between cold air and your body, helping you retain warmth. But it's not just for hygiene reasons that wearing underwear is important.

Merino Wool

Merino wool is the softest wool on the market, and because of its natural thermoregulating and moisture-wicking properties, it is a great choice for thermal underwear. It absorbs perspiration and pushes it to the outer layer, where it evaporates and kills odor-causing bacteria. Merino thermal wear is also designed with a seamless tubular design and covered elastic waistband to keep you comfortable and protected.

Merino wool is not cheap, however, and it's best to shop around. Some performance-oriented brands are experimenting with different blends. Odlo's Natural + Kinship Warm is a blend of 52% merino wool, 29% polyester, 13% polyamide, and 6% elastane. Black Diamond uses a manufactured thread woven with polyester for their Solution 150 Merino base layer.

Waffle Knit

Thermal underwear is a great choice when you're in the cold and need to stay warm. It is made from soft, breathable fabric that retains body heat, wicks away moisture, and prevents overheating. This type of thermal underwear is easy to slip on over your work pants or regular pants.

Thermals are also useful for spring and summer months, and you can wear them year-round, especially if they are made from cotton. The North Face, for example, sells waffle thermals called "All-Season" that combine cotton with elastane for warmth without suffocation. Waffle thermals are another great option to wear to the gym.

Another consideration when choosing thermal underwear is the weight. Wool is usually heavier than synthetic materials, so if you're going to be backcountry camping, you'll want to go with something a little lighter. However, most outdoor excursions do not require much weight, and this difference doesn't affect warmth much.

Cotton

Thermal underwear is available in a variety of fabrics and styles. Some are made from 100% cotton while others are made of microfiber. Both types are designed to keep your body warm. You should choose the type of fabric that works best for you. Microfiber thermal underwear is often form-fitting, while cotton thermal underwear tends to be looser. Both types require careful handling and care to maintain their shape and fit. To maintain the quality of your thermal underwear, wash it on a cold cycle in cold water. You should then lay it flat to dry. Do not hang it, as this can stretch the fabric and cause it to lose its shape.

When choosing thermal underwear, consider the activity that you'll be doing. If you'll be hiking or skiing in the winter, you may want to invest in a pair of thermal underwear that will keep your body warm while still allowing your skin to breathe. Thermal underwear can range in price from $25 to $110, depending on the size, quality, and brand. Consider the durability of the material, and read online reviews about the brand.

Carhartt's Rugged Flex Tech

If you're looking for thermal underwear with extra protection and breathable comfort, look no further than the base layer bottoms from Carhartt. The midweight waffle base layer pants are made with Rugged Flex fabric and feature a combination of Force and Flatlock seams for excellent moisture wicking and odor fighting. They also feature tagless labels and a brushed elastic waistband for added comfort and movement.
