Long johns are a type of underwear that extend down to the legs. They are typically made from a cotton or wool blend material and are meant to provide additional warmth. Some men prefer to wear long johns under their pants during the colder months, while others simply sleep in them.
There are also variations of long johns that include a button-up front, which can be worn as outerwear.

Thermajohn Men's Ultra Soft Thermal Underwear Long Johns Set with Fleece Lined 3X-Large Black
Mens thermal underwear is a lightweight thermal set of both a thermal top and bottom made of a poly-spandex material that will wick away moisture to keep you dry with no sticky or clammy feeling so you can wear them all day.
Made of premium fabric, thermals for men have smart odor control to prevent the spread of smells as well as absorbing odor-causing enzymes so they won’t stick to your skin. You can remain confident that wearing these all day won’t cause any problems.
Built with flexibility, the thermal underwear is highly stretchable to offer full mobility. The fabric won’t hinder your movements so you can move freely while at the gym, office, or home. They are perfect for all activities and will keep you comfortable.
Men thermal underwear set is soft against the skin, yet its strong seams won’t rip or tear prematurely, offering long life. They fit snug like a second skin for perfect heat retention minimizing heat loss for an ideal base layer or worn on their own.
For even more added comfort, long johns for men thermal have no tags, which reduces any skin irritation. You can slip them on and off easily and can be worn under your clothes for added insulation and at the gym for added support and movement.
WARM Cotton-rich Thermal Pants are ideal for everyday warmth during low activity levels. Our famous dual-layer technology traps air between two thermal layers creating a barrier against cold temps. C Vapor technology wicks sweat away from skin for drier, cooler comfort.
Close-to-body fit allows for easy layering. Soft cotton/polyester blend with smooth, flatlocked seams.
The double layered Expedition Baselayer Pants keeps me warm while walking on the beach with the wind whipping and waves crashing around me as well as sleeping snuggly in bed. My recent purchases were to add to the first one I bought 2 winters ago.
The original one is still in excellent shape, no loose threads, no wear marks, or any negative attributes other than slightly faded. I’m expecting the same performance from the four new ones I recently purchased.
An additional benefit for me is the added level of leg compression the double layer pants over all of the single layer baselayer pants I own by Duofold as well as several different other companies.

I bought this top with the matching bottom in large for my husband for our trip to upper New York in the freezing snow and ice of late December. We live in sunny Texas. The bottoms work fine. The top is not cut well.
The depth of the sleeves is huge! I mean really enormous. The rest of the top (size large) fits ok around the body but the sleeves are so deep and the armholes so enormous that they are totally out of proportion except perhaps for a steroid-laden body builder.
They bunch up under shirts and sweaters. However I had to keep this and not return as we had to have it for the trip. It worked, for sure. The thermals kept my husband toasty warm in freezing conditions.
He looked odd though, at times, with the thick bunching thermal underneath his outer clothes. The cut needs adjusting for normal mortals without huge biceps.
I bought this set for my husband as we were looking for a cotton product. He absolutely loves the feeling on his skin as it is soft and not rough and scratchy. We will definitely consider The Vermont Company next time we are in need of such product.
I have two similar shirts in medium from a few years ago, so I ordered a medium. It is skin tight. I’m a woman 5′ 4″ and 120 lbs. It’s kind of stiff, scratchy material, and if it doesn’t fit now, there is no way I’d put it in the dryer, even on extra low.
I’ve returned it for an XL. Obviously the sizing is way off. Hoping that fits better and that it will soften up in the washer and dryer. Overall disappointed, but since I have to pay return shipping, I’d rather get another shirt than have nothing to show for the $6.

Been searching for these for a while. Great price. Ordered size SMALL for my husband who’s muscular in shape and has a 28 inch waist. The fit is perfect. The length is great and the ankle cuffs have a nice stretch to them.
The ankle cuffs are soft and stretchy but they don’t stretch like plain cotton because of the elastine in the cuffs with the cotton ribbing. The legs are the waffle pattern. The waist has a a soft layer inside the part that stays against your skin.
It’s not scratchy. Husband loves them. They keep him warm when working outside and hiking out in the cold. He also works outside for work and these keep him warm all day. He says they’re very comfortable.
They look exactly as pictured and we ordered the Light Grey Heather.

An antimicrobial finish helps keep the bottom feeling and smelling fresher longer, too.
I’m a 36” waist and the waist band has to really stretch. I don’t know how a 38” person would handle it. Also will see how warm they are. When it says thermal, I was expecting the heavier waffle cloth underwear.
I would put 4.5 out of 5 because of its quality, comfortability and fit. However the only thing I did not like was its waistband. Not happy with the quality and the width of the waistband.

Good fit,good feel! A good gift!\nPerhaps the designers will consider a more convenient “rear exit” addition! Yet it is quite comfortable & well suited for me!\nMany thanks!
My union suit is warm and the front zippers are a nice feature. I’m greatly thankful for it. My only quip is I’m a little to tall for the fit but it still does the job. Thanks.
It’s hard to wear anything else now I own this. My friend bought one after seeing mine, they’re great. I think I’ll have to get another for when mine is in the wash.

These union suits are a must if you live in a Winter cold climate! I’m from Wisconsin and work outdoors in all seasons. Spending most of the day in the cold you need to be protected from the elements.
For myself, this union suit is the “first line of defense” in my Winter wardrobe. It’s thermal and combined with layers, I’m warm all day long. Being one piece, they don’t ride up when you bend over or move around.
And I might add, they do make great nightwear as well.
Great fit I’m 5’11’ 130 lbs and the size medium fits great, awesome to sleep in as well as fitting under jeans or around the house. The back door I probably will never use would be great if it was an option.
This is my first onsie thermal and I really like it compared to thermal pants not having a waist band to constantly keep pulling up or digging in makes it extremely comfortable easy to put on and take off.
Awesome one piece for when it’s cold outside! My hubby liked the booty hole especially lol we had a good laugh when he tried it on for the first time. He said it reminds him of a big blue condom. but in all seriously it’s a nice product will buy again when this one rips haha.

I bought these after reading the reviews which are wrong. Out of the package they are soft, comfortable and appear to be well made. Don’t get fooled by their appearance! They stretched out of shape after wearing for only a few hours as did the tops.
I’m not sure why the reviews are so good for these when the exact opposite is true. Do not buy these. I washed and dried them hoping they would shrink, but no such luck. Disappointed in Cali!.
These are great under my nylon uniform pants on cold days and nights. The nylon long johns gave me hives that itched for weeks! The cotton ones are comfortable and don’t make me itch! I got 4 pairs. So I may never need to order again.
These fitted long johns are cut from a soft and stretchy tech blend that keeps you warm outdoors without overheating indoors. A signature Quick Draw fly means easy convenience. Style Number: 5680689.
Don’t let the light weight of these fool you. They really keep you extra warm and layer easily under clothing without adding bulk. Bought the top too. Super pleased !

There are a variety of long johns for men on the market, and each has its own unique features. When choosing the right pair of long johns for your needs, it is important to consider the climate you will be wearing them in, the activities you will be doing while wearing them, and your personal preferences.
Some of the most popular materials for long johns include wool, cotton, and synthetic blends. Each of these materials has its own advantages and disadvantages, so it is important to choose the right material for your needs.
Wool is a great material for long johns because it is extremely warm and durable. However, wool can be itchy and uncomfortable for some people, and it is not as breathable as other materials.
Cotton is a more affordable option than wool, and it is also more comfortable for most people. However, cotton does not insulate as well as wool and can become wet and cold when exposed to moisture.
Synthetic blends are a good option for people who want the benefits of both wool and cotton. Synthetic blends are usually more breathable than wool and more insulating than cotton. However, they can be more expensive than either wool or cotton.
When choosing the right pair of long johns for your needs, it is important to try on a variety of styles and materials to find the ones that are right for you. With so many options available, you are sure to find the perfect pair of long johns for your needs.
