Long Johns Buyers Guide

Now that you’ve seen the best long johns on our list, you’re one step closer to staying warm this season. However, although we managed to narrow it down to just ten choices, you might be on the fence between a few.

You might even have a few questions about long johns in general, so we made a buyer’s guide and breakdown to help you figure it all out. Enjoy!

What materials should long johns be made out of?

Generally speaking, there are two combinations of materials used in most modern long johns. You’ll be able to choose from either spandex and polyester or polyester and cotton. Spandex and polyester is a great combination for people who want the moisture-wicking properties paired with stretchiness and flexibility to prevent your movements from being restricted.

On the other hand, cotton and polyester is a much better combination for overall warmth in super cold environments. Ultimately, the choice is yours. The real question is; What combination best suits your activities and local weather?

What are long johns used for?

Long johns were originally just a second pair of clothing to wear underneath everything else for warmth purposes. However, these days they serve two purposes. While many people still prefer the spandex and polyester options for underwear in cold weather climates, there are also plenty of options that double as a pair of pajamas.

Wouldn’t it be nice to have long johns that you could dress up over without having to change every time you got home or went out with friends? Depending on which set on our list that you pick, you could wear them for either or!

Expert Tip

If you’re heading out into any area that’s extra cold, tuck the long johns’ shirt into the pants that came with them. This will further prevent body heat from escaping, which will keep you even warmer.

Did You Know?

Long johns are named after a man who wore similar clothing to what we see today way back in the 19th century. After decades of name changes and different variations, they were settled as long johns. The overall appearance might not have changed too much, but the fabric used, and the pattern designs have evolved to a level that most clothing hasn’t.

If you’re looking for a comfortable, affordable, multi-purpose pair of clothes to stay warm any time of the year, then your best bet is to try out a pair of long johns.

Out of the countless reviews that we looked through, the options that you see above-reigned supreme. Let us know what you think of our picks, and which ones you decided to go with. Don’t forget to consult the buyer’s guide for some help if you get stuck between two pairs!
