"I bought this shirt (Medium size) for my mom, and going to send it to her as a gift ( a week earlier got the same shirt but in S based on reviews, thinking it comes bigger than expected. There is a white brand-name small label on a left sleeve, near the wrist."
"I'm pretty particular about fabrics and neckline--I can't stand anything really tight around the neck."
"I work outside a lot and the thermal works very well and easy to layer over."
"this is a great shirt.. keep an eye on the price.. it changes often .. it's really one of the best of its kind.. keeps my always cold women warm, and it doesn't stay damp if you sweat .. she has 3 of them.. wears them as undershirts."
"Fits good everywhere - shoulders, bust, waist, length, but the arms are about 1-1/2" too short at 5'-7", so I'm either tugging them down a bit or scrunching them up."
"Okay - I am 5'8 and the sleeves were short on me, but I liked that, because the ends of the thermal sleeves did not stick out from my sweater."
"I do think it works to keep me warm; was worried not to order too large; now I wish I had, for despite cold water washing and air drying, I believe it has shrunk...so I would advise getting it one size larger than you need..."

Lightweight yet incredibly strong, the silk jersey knit is supple and sumptuous with a natural stretch for all day comfort and an attractively-shaped pointelle pattern. 100% Sik.

"The length of the top and sleeves are kind of short, but the good thing is, this allows me to hide it under any of my jackets/sweaters/hoodies. The waist of the pants didn't give me a loose fit as most size M does, but I didn't feel uncomfortable at all. I wear the bottom underneath my pants a few days ago when it’s lower than 35 F degree outside. They don’t make me feel too hot when I wear them to sleep and with heat open."
"I hate wearing layers usually but these are thin enough and my clothes slide over them very easily while keeping me warm."
"It came timely and it warm enough for 40s, maybe 30s, under jeans of course!"
"The only thing is I personally wanted thermals that were lighter and little looser to wear around the house."
"This was a gift to my 86yo grandma, who is particular when it comes to fabrics on her skin."
"I ordered two sizes and two colors, I got two totally different packages and the items themselves and very very different."
"I read the fit recommendation that stated the fit was smaller than expected so I bought the set 2 sizes larger."
