Second Skin
(Original review, update below) I'm in love. I was fed up with the old style waffle weave longjohns I have, and after reading reviews, tried Thermajanes. First shock - they fit perfectly, which never happens to me; second shock - they are comfortable to lounge around in while inside the house without getting too warm, but still keep me warmer when outside. Super soft on the skin, but slinky to the touch on the outside so they don't get bound up with your outer layers. You forget you are wearing longjohns until you take them off - which feels like peeling off a soft second skin, and you immediately miss having them on. I bought five more! Update March 18, 2025: I have lived in these for two and half months, and have some observations. First, they shrink a little when washed, I don't know if it's a whole size difference, but noticeable. The fabric is stretchy so this isn't a deal breaker. The color of the fabric determines whether or not the fabric pills - the black is still as smooth as when I pulled it out of the package, but the grey was visably pilled and textured after three washes. The lighter colors seem worse, but in spite of the pilling, it doesn't seem to attract and bind with other colors in the wash so you don't have grey bits on a white top for example, and when fully pilled, is still comfortable to the touch just no longer sleek. The fabric is not inclined to snag at all - a bonus with my cats!! One odd point is I can feel the Thermajanes on my knees when wearing under loose pants, but don't notice Thermajanes anywhere else on my body with or without additional clothes. Finally, construction of the garments vary - black, grey, and pink for example are standard hidden seam, but light blue and white are exposed seams with the fabric edges zigzagged together flat. If you wear these as truly underclothes, it doesn't matter, but since I wear the tops as every day clothes, I prefer the more finished look of the hidden seams. I still recommend Thermajanes, but with the caveats mentioned above. YMMV.

Great for working outside
My daughter absolutely loves the Thermajane Black Turtleneck! She works in fast food and is often outside during the winter. This thermal turtleneck has been a game changer for her. She wears it every day under her uniform and says it keeps her warm without feeling bulky. The fabric is soft, stretchy, and breathable, making it comfortable for long shifts, whether she's inside or outside. The fit is perfect—she’s wearing a Small, and it fits just right while still allowing enough movement for her to work easily. The black color is sleek and versatile, so she can pair it with anything. This shirt has made her much more comfortable on those cold winter days. If you're looking for a warm, cozy, and durable turtleneck for cold weather, I highly recommend this one!

Perfect base layer for winter!
Exactly what I wanted for a base layer during winter. Lightweight but warm, and they washed beautifully. So soft against the skin. Highly recommend!

Great shirt, just don’t buy “red” unless you want maroon
I love these shirts. They are warm and fit great. I have them in several colors, however, the red is definitely not red. It’s a dark maroon. I’m a Georgia fan and bought this wear with my game day attire but I refuse to be out here looking like an Alabama fan.

Comfortable and Warm - but pills terribly!
I was hoping to use this to layer with a cute wool coat, but it will only be good hidden completely from view because it pilled terribly after just the first wash. It got worse after I wore it and again even worse after the second wash. If you don't plan to let any of it show, it is a nice, comfortable, warm shirt that fits well, but I won't purchase again. I have a similar shirt in another brand that has zero pilling after several wears and washes.

Funny Story - My Bad
I ordered this shirt as a layering piece. We were experiencing a cold snap and I was going to be outside for an event and needed something underneath my shirt to help keep me warm. I thought I ordered this shirt in my normal size (2XL - 3XL) but when I received the shirt I noticed it was really small. I chalked it up to being a layering piece so obviously it should fit a little tight. I tried it on and while it wasn't the most flattering, and would NEVER be worn without a shirt over it, it fit fine in the arms, sleeve length and all around. I don't like things tight on me this wasn't too bad. Later on, when I was laying my clothes out for the next day, I really looked at this shirt and noticed that I had actually ordered a size SMALL. My reaction was two-fold: first, I laughed at myself because of course I ordered the wrong size but, second, I was pleasantly because I actually fit in a small. Lesson learned but the shirt was great, did what I needed it to do and was comfortable. Next time I order, if it is a layering piece, I will order a medium or large to give myself some more room but, needless to say, I recommend this product - just consider the sizing.

Love this brand!
I lost alot of weight so none of my thermals fit like they should anymore. I love this brand so i knew I was going to order from them again. I am 5'4, 145 and a 38DDD. I bought this in a medium. While it is a bit snug in the chest area, it is not at all uncomfortable. The length is perfect and the sleeves our even a bit longer, but I love that! I hate when I layer and my sleeves get lost underneath. I just wish they'd put in thumb holes for all layer tops, but that's just me being dramatic. The waist is a bit loose but honestly it's not even something I'd complain about because all my tops fit me like that due to my chest size. This shirt is comfortable, cozy and breathable. Zero restrictions and whatever this magical material is, I never feel like it sticks to my outer layer. Buy this brand. Their product is serious amazing. And I own alot of name brand base layers and this Is definitely the one I always find myself reaching for. Oh. And they are not see thru. So you can always wear this as a shirt if you end up indoors and want to take off your outer layers. It's definitely a staple in my closet. And the pants are phenomenal as well.
