The thermal underwear industry has become relatively lucrative over the years. With all the sales, you may be skeptical over whether or not thermal underwear or bottoms do what they say they do. After all, the thermal underwear of today isn’t the same as your grandparent’s thermals. They’re not the same as when they were first designed. Do they work? The answer is yes, but it helps to know how they work so you can get the most of your new thermals.
How Thermals Work
For thermals to work in keeping you warm, dry, and comfortable in the cold to extreme temperatures, there are some things to consider. You’ll want to get the most out of them. Thermal underwear is excellent and works well. You wish to view material, fit, moisture-wicking, heat retention, and layering before buying your thermal underwear or bottoms.
• Material: The best material for your thermals will be Merino wool, synthetic blends like polyester/spandex, or silk. Cotton may feel comfortable but will absorb and retain moisture which will cause a lot of problems in the cold. Synthetic blends will be more cost-effective and work as well, if not better than natural fibers.
• Fit: For your thermals to work correctly, they need to fit well. This means a snug fit or popularly known as fitting like a second skin. Thermals will move and stretch with your body to prevent any movement hindered by wearing them.
• Moisture-wicking: Your thermals should wick away moisture. Staying dry is essential when you’re out in cold weather, and your base layer of thermals needs to pull sweat from your body and release it through the breathable fabric. Most fabrics will do this except for cotton.
• Heat Retention: Staying warm is the whole point of wearing thermals. Whether you’re wearing a thermal top or leggings, you want to stay warm. Thermals distribute your body heat across your skin and hold it there as they work as an insulating layer. The snug fit keeps this heat from escaping and cold air from entering.
• Layering: While thermals work great on their own, they need help when the temperature gets too cold for thermals to be worn on their own. Additional layers will help add extra insulation and protection against the wind and water. When choosing an outer layer, look for something that is water and wind-resistant or proof. Thermals will provide the base layer and foundation for staying warm.
Thermals do work but making sure they fit correctly and making the suitable fabric will enhance their benefits and help you. As winter approaches and the temperature drops, you’ll soon become a believer in the world of thermals and may find yourself purchasing a few extra pairs to save yourself laundry time.
