Carhartt Men's MUS130 Classic Union Suit

Whats most important to know about ordering these is that selecting a different color selects a different style and therefore a totally different garment. The red union suit has buttons and a slit in the back, is made with heavyweight cotton, and has close fitting cuffs and ankles. The black union suits are made of lightweight, waffle type cotton and polyester, (like the older style two piece thermal underwear), have snap button closures, do not fit snugly around the cuffs or ankles like the red style, and in the back have a separation of the union suit with an elastic band that allows you to tuck in the upper piece. More on this below.The red, heavier weight cotton version I find to be extremely comfortable, very warm in cold weather, and overall more comfortable than the black style. The ankle and cuff closure are thick and elastic and make putting on clothes less aggravating as they hold the sleeves and legs from riding up as you are getting dressed.They are more suited for colder weather than the black style and DO have a flap in the back for those who would use it. They wick moisture away and I find them to be the most comfortable of the two styles.The black style is more suited for milder cold weather. I like the snap style buttons better on these but thats where it ends. As one reviewer stated about the buttons on the other style, they sometimes are not the right size and need to either be replaced or have someone sew up the button hole as they come unbuttoned. But most annoying of the black style is the rear separation of the upper and lower with the elastic band. (Look at the pictures provided by Amazon) It is like it is a one piece in the front and a two piece in the back. Plus it is impossible to use the bathroom without taking them off on the top and that makes them inconvenient. I find that if it is anything below freezing they are too lightweight and if it is above 50 F they feel uncomfortable as they don’t wick moisture away as easily.Carhartt is known for durable, long lasting clothing and the red style is in line with their usual quality. I bought the red style first and love them. I mistakenly bought the black style thinking they were just like the red style and I never wear them unless it is mild or my red ones are dirty. I DO wish the red style had the snap closure, but beyond that I love them. Look at the pictures provided by Amazon carefully and you will see the difference in the two styles. It is misleading to most and I wasted my money on the black style.

I've never had a union suit before, so I didn't have anything to compare these to exactly, but I have owned thermal underwear and I am a fan of Carhartt's products. The quality of Carhartt is always seen in their products, and the union suit is no exception. The seems are sewn up in Carhartt's traditional fashion with multi-stitching to ensure that they do not come undone. The cuffs are perfect because they are not like usual cuffs that you may see on a coat, jacket, or hoodie. The cuffs are almost twice as long as you would traditionally think, and this is perfect because they allow other clothing to easy slide down your arms and up your legs without the union suit bunching up underneath.The most interesting thing I found about the union suit was the button-up system. It was well thought out and works rather well. The buttons allow you to unbutton all the way down to the crotch area. This makes it extremely easy to get in and out of the union suit. The spacing of the buttons is well planned out as well because there are just enough to ensure that it doesn't leave any area uncovered, but not too many to be a nuisance to unbutton. Additionally, they even thought out using the restroom for a number two because there is even a button in the rear if that situation ever arises.Again, without knowing what to expect with an all in one kind of underwear, I really enjoy the comfort and warmth these provide while I'm working outside in the freezing cold. The mid-weight cotton design is perfect for the freezing cold weather, and works perfectly with my normal clothes and other cold weather gear such as coats and bibs. They are thinner so your layers aren't too thick and cause you not to be able to move when you bundle up. Additionally, they provide extra length in your arms and legs. I really enjoy this because I don't have to worry about stretching out and not being able to move or causing the sleeves or legs to pull up on my arms and legs.

Was hesitated because of the price. However, after I purchased and received package, I was more than satisfied. The material quality and wearability justified for the price. My favorite part is the locker loop design, it helps tighten up the extra length. I’m 5’7” and 135lbs, it fits me perfectly.

This is a good union suit for the price. I am 6'2" and weigh around 275, so I ordered the XXL size. Since I am long through the torso, it seems like when I pull it on over my shoulder that the overall length of it is a bit lacking for my torso length. If you tend to be more "leggy" or under 6 feet tall, it will probably be proportioned better for you.There is a problem with the buttons wanting to come loose within the first or second wearing. I've had to have my wife sew 3 of them back on already and a 4th one is now coming loose. With so many buttons on a union suit, it's a shame that these are coming loose so soon. It is an industry wide problem with buttons coming loose on garments, but this is way too fast. I am waiting for the day when the garment industry finds a way to better secure buttons on all garments. Who wants to spend time sewing them back on simply because they were not well attached in the first place.That matter aside, this is a good union suit that will keep you warm and comfy. Just watch out for any buttons coming loose and sew them on more securely or you'll lose them.
