Whether you like engaging in outdoor activities or you just find it difficult to stay warm when the temperature lowers, it is essential that you have access to the best clothing possible. Wearing a layer of thermal clothing is usually a good idea when spending time outdoors, since adding or removing layers may help keep you warm or cool depending on the weather and activity.
I’m curious, though: what, precisely, is thermal apparel? In what way does it work? And why should we put it to such use? This blog post by Chums delves deeply into the topic of thermal clothing, covering everything from thermal trousers and underwear to fleece-lined jackets and boots.
In what ways are thermal garments useful?
If you want to maintain your body at a comfortable temperature, even while it’s chilly outside, you need thermal apparel. Thermal shirts, coats, leggings, jackets, and boots are all examples of the kind of outerwear designed to help keep one warm in the cold. The idea behind these garments is to keep the wearer warm while allowing excess sweat to evaporate. In the next posts, we’ll go into this topic more.
While many different types of people use thermal gear for many different purposes, winter outdoor enthusiasts are by far the most common users. Some outdoor pursuits need thermal clothing, including:
- Snow sports like snowboarding and skiing
- On the ice, skating
- Winter running/jogging
- Walking in the Woods/Rambling Up a Mountain
- Dog Walking
- Attending sporting events (outdoor football and rugby matches, etc.)
- Brave the cold and do your shopping in the great outdoors! (Christmas shopping, Christmas markets, etc.)
As we’ll see later, thermal clothing’s permeability aids in wicking away perspiration from the skin’s surface. Therefore, in certain higher climates, thermal clothing may be an ideal choice when worn without extra layers on top. Therefore, regardless of the season, athletes always compete in base layer thermal gear.
Does using heated underwear really warm you up?
Simply said, you could find that thermal apparel works wonders for keeping you warm. When venturing out into the cold, you may protect your extremities, organs, and even your head with thermal wear. It’s important to remember that this gear won’t really warm you up; rather, it will prevent you from becoming cold. It may seem like splitting hairs, but in reality, there is quite a bit of nuance here.
By trapping your own body heat, thermal clothing makes even the coldest of outdoor excursions bearable. As it may take your body longer to generate enough heat for the thermal clothing to retain, the thermal gear may not work as effectively if you are already cold when you put it on.
When worn, how does thermal clothing work?
Thermal clothing works by providing a second layer of smart material to an individual’s typical outdoor attire. Two-ply fabrics like wool, fleece, polyester, nylon, silk, spandex, and smart cotton blends are often used in these garments so that more of the wearer’s body heat may be retained. If you can generate more internal heat, you’ll be better able to keep the cold air outside out of your body.
These ingenious devices do double duty by insulating the wearer from cold air and dampness. This is because thermal clothing is constructed from breathable fabrics that work to wick moisture away from the skin. In the same way that a candlewick draws oil from a lamp and up the fabric to be lighted, the materials used to make thermal clothing gather sweat and transmit it away from the skin’s surface. This prevents the user from becoming clammy and hence much colder.
In what ways can clothing contribute to body heat retention?
Clothing is considered thermal if it is able to both retain the wearer’s natural body heat and wick away moisture. The greatest thermal fabrics are often synthetic, although wool, cotton, and even silk are all thermal in the sense that they keep you warm in the cold. Fabric mixes like spandex, nylon, lycra, and polyester may give an excellent combination of warmth, heat retention, and moisture-repelling characteristics, in contrast to certain natural textiles which can feel scratchy or retain moisture. This is the key to a warm and cozy garment.
