Comfy and Warm
Bought these for my boyfriend since he works outside and he loves them, even lounges in them around the house. They fit fine, for reference we got him an XL and he is 6'1" and skinny. They may be a smidgen long but if we had sized down the sleeves would have been short on him, as he has long limbs. Think skinny tree and that's my man, haha. They definitely help keep him warm without him feeling constricted which is great for the work he does. We'll be buying a few more pairs soon!

very nice Union suit underwear
this a very comfortable, good looking, warm and great fitting. the fabric is not too thin or thick and feels very soft and the rear flap works great. I have used many other brands but these are one of my favorite now

Nice Gear but Lots of Buttons
Functions well as expected - buttons are a bit small and problematic to close.

All good.
Suit was priced good. It fit to size and was delivered earlier than expected.

Arrived quickly, good price, comfortable
It is not deeply cold, yet, and so this first "union suit" for me has not really been tested for cold. But i am mostly pleased at how it fits me. My belly is a bit out of whack compared to the rest of me, and as such the buttons are a bit stretched around my middle, leaving slight gaps between buttons, while the rest of the suit fits well and is very comfortable. And they are easy for me to get in and out of, even with stiff inflamed joints etc. The rear flap is even within my reach, so I can use it and avoid removing suit for restroom visits. The arms may be a little short, and my arms are not particularly long, but this is a plus if you do not want the sleeves showing beyond your long sleeve shirt. The sleeve cuff fits snugly keeping sleeve in place while donning a shirt, and keeps air flow out. I haven't worked really hard in the suit yet. so have not really tested wicking properties, but so far so good. Movement is good, plenty of room for action, without stressing seams etc. I ordered another brand/style of union suit at the same time, a week later it has not arrived yet. The other set is planned for more severe weather, or longer wear situations and at twice the price, I expect them to be nicer, but that said, I think I will order another suit like this to have one in wash while wearing the other, and for most situations these will suit me quite well. I wear bib overalls a lot, do to discomfort of tight belts, and not having tight under garment elastic waist is really the comfort factor I was hoping for, and these are great on that account.

Too Expensive
Sent back before I could try them on but the price is outrageously high for what they are.

Well made, soft and warm
Now my favorite winter inner layer, because the fabric is so soft! Warm yet not too bulky, breathable. Construction is really nice, with secure seams and well finished buttonholes & buttons. Buttons more closely spaced than other union suits I have. Garments show minimal shrinkage and no pilling or seam issues after multiple cold water machine washes and medium heat dryings. If you are 2x and have longer arms, you might want to check specs. The legs have generous length but the arms are not as long as some other makers' 2x. Love this item, all Mixhigan winter long and half the spring and fall!! I never want to wear my other brands again. So soft.

Warmth is bliss
They are comfortable, fit well, did not shrink, very warm, but I wish they were pearl snap instead of buttons. Highly recommend if you have to be outdoors working and don't want a bunch of bulky clothes to stay warm!
