Great product but order normal size
After reading all the reviews I ordered up a size for my son who normally wears a medium. I ordered a large and it was definitely too big. It will work fine and itโs not worth the hassle of exchanging. But he would have been just fine getting the regular size he wears. Other than that the product is great and exactly what he was wanting. Wears it to play baseball in for his cold games and these are soft, comfortable and will definitely keep him warm.

Nice and warm, comfortable if a bit long for me.
I'm 5'7" and 140~ pounds. Ordering a medium, both top and bottom fit comfortably although both are a bit long for my frame. I wouldn't get the small as it would most likely be too tight. The color matches the photo well. The inner lining is soft and warm. I've worn these outside with sweats, long sleeve tech shirt and hoodie in 15-20 degrees F and been quite comfortable while staying active.

Soft, Great Fit and Very Warm
My husband absolutely loves this set. He is 6'3" and really skinny. He always has an issue with clothes fitting comfortably but still being long enough for his arms and legs. The Small fit him perfectly and stretches nicely to fit his long limbs.

Great purchase
Ordered a size up as suggested by other reviews and fit my my husband perfectly. I did the same for myself and the size fit. Very warm and comfortable! Would purchase again!

Order 2 sizes up!
Luckily I read the reviews before purchasing. My husband is 205 lbs, 5'9" and average build. He usually wears a L. I ordered the XL and 2XL so that he could go with the one that fit best. He went with the 2XL! They were a little long on him but he liked everything else about the thermals. He gets hot easily but with these he stayed perfectly comfortable skiing in single digit temperatures.

Top and bottom are same size
Unfortunately the pack comes as one size. I needed a medium bottom and a large top. The top is tight but the bottom is fine. I kept them but probably wonโt wear the shirt

2x does not fit 2x
this item well made however sizing is way off....2x is more like a large. the thermal top could possibly be long enough for someone who is tall but SLIM. the thermal bottoms could be big enough probably someone up to 6 ft 4 " tall if they were not very stout (chubby). I normally buy 2 or 3 x for my very tall son with 40 inch waist at Walmart. but this set is no where near fitting him....nice quality though I am sure.
