The base for any clothes layering system is going to start with your base layer. This is the foundation that all the other layers are going to build upon. If you live near the Arctic or plan on spending some time in arctic conditions, you will need a good thermal base layer. Thermal underwear is the perfect accessory to keep you warm and dry in colder climates.
Thermal underwear is going to be the clothing layer that fits snug against your skin. It has two jobs: The first one is going to be to keep you warm and the other equally important job is its moisture-wicking ability so you can stay dry. No one wants to be cold and wet at the same time. This can be especially dangerous in colder temperatures, precisely arctic conditions.
Even in colder conditions, you can't sweat. This is why having thermal underwear will help keep you dry even in colder climates. These thermal underwear will work as an insulating layer keeping you warm and make it easier for the perspiration to escape through the wool fabric. This adds to your overall comfort, warmth, and dryness. Having a base layer of thermal underwear on will also help your additional layers work even better.
While layering is essential, you don't want to have too many bulky layers on. Being able to move is extremely important, and thermals for women are made of a stretchable fabric to continue to have that freedom of movement you enjoy. Another thing to consider when purchasing thermal underwear for your Arctic expedition is that, you would want to look at the type of fabric that they are made of.
Most modern thermals will be made of a natural fiber like Merino wool or a synthetic fabric like polyester, often blended with spandex for added flexibility. Both of these have excellent insulating properties and have proven efficient in working away moisture from your skin.
There is a cost difference, so synthetic fabric thermals will be your best bet if you are on a budget. It also makes them easier to take care of in the laundry. When it comes to thermals, it is best to avoid cotton at all costs. Cotton will absorb and retain the moisture, which can prove extremely dangerous in an Arctic condition. Some of the things you want to avoid are frostbite and even hypothermia. If you're wearing cotton, you have a higher chance of dealing with those two issues because cotton absorbs moisture.
When it comes to living in an Arctic area or just dealing with the cold conditions in general, a good set of thermals will help keep you warm, dry, and comfortable. Having a few extra pairs on hand will make doing laundry at the end of the week more manageable, and if you need to, you can also double up on your thermals. They are lightweight and fit snug against your skin, so you will not have to worry about heat escaping or cold getting inside.
