Winter is almost here, and we have to be prepared for it. Preparations mean getting warm clothing as it can get chilly during long winter seasons. Bodtek offers a range of thermals in different colors and designs to help keep you insulated.

When it comes to thermals, the terms thermal underwear and long johns are commonly used. Are these terms the same? If not, what is the difference between the two? In this article, we'll discuss thermal underwear versus long johns.

Appearance
There is not much difference between thermal underwear and long johns. It all depends on where you come from and your preference. Some people call these underwear long johns, while others call them thermal underwear. People started calling them long johns after John Lawrence Sullivan (Boston Strong Boy), an Irish-American boxer, decided to enter the ring to face his opponent while wearing two-piece thermal underwear. People started calling them John Ls, and later long johns. Because they have long sleeves and long legs, the name long johns stuck. A significant number of people call them thermal underwear due to their insulating ability during the cold months.
 
Fabric
The material used in thermals is important because it determines their durability and comfort. The fabric that Bodtek uses to make thermals is 92% polyester and 8% spandex, making their long johns most ideal for cold and cool weather. This also makes them ultra-soft, snugly, and comfortable. Polyester has good wicking properties, resulting in more comfortable workouts and outdoor activities during the winter. The moisture-wicking technology also allows your skin to breathe with ease, increasing the levels of comfort while leaving you odor-free.

Function
People use thermal underwear or long johns to stay warm in cold weather. They are often worn under other clothing to trap heat. The long johns and thermal underwear are a favorite to many due to the fact they are not bulky. The ultra-lightweight feature is due to the latest technology used to make the fabric.

Conclusion
Guess what? Even the designers can’t seem to tell if there is a difference between the long johns and thermal underwear. Whether you choose to call them long johns or thermal underwear, they aim to serve the same purpose. They are lightweight, and you can wear them underneath your trendy daily wear.

So what is the difference between thermal underwear and long johns? The answer is there is none.
