When you’re looking for a thermal underwear that is practical, warm, and provides utmost comfort, look no further than this Fruit of the Loom Premium Men’s Thermal Union Suit. This full-body thermal offers a one-piece solution that provides a bulk-free fitted style perfect for layering and built for lasting protection, warmth, and comfort in cold conditions, day or night. Made from soft cotton and recycled polyester rib fabric, it stretches for a better fit, which won’t restrict your movements, plus the natural breathability of cotton will keep you dry while providing maximum heat retention. A full-length button closure up front makes it a breeze to put on or off, and the button back opening provides practicality when you need it. Rib cuffs at the wrists and ankles ensure heat stays trapped as much as possible, and the tag-free neck label plus flat seams prevent chafing and enhance overall comfort. If you prefer the convenience of a one-piece thermal, this Fruit of the Loom Premium Men’s Thermal Union Suit is a must-have in your wardrobe. Review: Comfortable fit & warm - Fit well, very warm & wash and dry very well. Durable & I will purchase two more pairs! Review: Super comfortable, Easy to Wash and No Itch - This is exactly what I was looking for. The individual thermal tshirts never seem long enough, and the pants are never comfortable. This suit is perfect. It's warm, comfortable, and easy to toss in the washer/dryer. I bought a size up because I can't stand any clothing that's skin-tight. It's loose, and bit long in the body - but what I would expect from sizing up. Didn't shrink in the wash, and the seams appear to be well sewn. Was so happy, I bought a second color a few weeks later.

The Union Suit used to be very popular for important reasons
My preference would have been for 100% natural fiber, but this cotton-poly blend is actually quite nice against my skin. In my ongoing quest to free my waist from binding, this feels so relaxing. It's not heavy weight, but my core isn't split at the waist, so core heat has stayed cozy. Despite connecting in the middle, the stitch rather small and durable, and it opens plenty in the front and back for doing one's bathroom business. Speaking of, if one would like to feel very cozy and warm while doing said business, one probably would like this. At this cost, maybe just try it. Here's why it didn't rate 5 stars for me. It is sewn together at the very center of the crotch. The buttons at the bottom are not easy to feel. 5 stars would have been given to: 100% cotton; completely unbuttons at bottom; and buttons are snaps. Then again, the only similar garment I found with those qualities goes for over $100, and would have to be imported from the UK, so...yeah.

Good fit
I am 5'9" and a lean 145 lbs. I normally wear 30/32 pants and large tall shirt. This union suit fits me very well. I can raise my arms and legs without it creeping up my calves nor forearms. It's snug, but not tight, through the shoulders and chest, and a little baggy in the waist. I am well pleased with this purchase.

The Good, The Bad, & The Ugly
First, I'm 5'11", & skinny. Bought this strictly for wearing at home. THE GOOD: Overall, pretty good fit, & comfy. Nice, small sleeve cuffs & ankle cuffs which fit my little needle wrists & ankles nicely. Unless you're a stick-man like me, however, they may be too tight. Arms & legs are plenty long enough! THE BAD: As others have mentioned, torso is WAY too long. Should be about 6-8 inches shorter. Because of all the excess material in the crotch area, it would all bunch up in pants if I wore it that way, but I only wear this as PJs, or under sweats around the house, so not a major issue, but would still be nice if proportions were better. Also, material is THIN! This is NOT thermal, by ANY means. It is basically, a t-shirt body suit. THE UGLY: Crotch WAY too low, as others have mentioned. And that horrible rear-end opening with one button! A traditional 2-button flap would be a HUGE improvement! That said, for me, it was not a major issue, as I'm only using this thing at home, so I had a seamstress sew the entire opening shut, & I don't mind peeling it down to use the toilet. Would I buy this again? Maybe, but only at about half the regular price.

仕様なのか分かりませんが、通常時でもおしりの部分がガバガバです。 それ以外のフィット感や質感は良きです。
