Review for model:

The material seemed thin but fulfills its function perfectly, it's not overly tight, gives a bit of "looseness". For me, the elastic waistband doesn't work very well, but it was enough to replace it with a string and now it holds as it should.

The material and size match the description, but the cut of the trousers is unusual: at the front they are wider than standard, while at the back they are very narrow, as if no room was allowed for the buttocks. As a result, when bending over, the trousers slip down from the waist at the back.

When I started my military service in my youth, I received 6 sets of warm underwear of 3 different types. Currently, I am satisfied with 2 types of American third-generation warm underwear – the 'ninja' and the 'waffle'. First of all, this is level 1. Great fabric, nice cut, wicks moisture well and stabilizes during physical exertion. I recommend it to everyone!

Exactly what I was looking for. Warm, comfortable, and something that surprised me – LIGHT. Really light underwear, so much so that you forget you're even wearing it. Fits true to the description.

The first impression after unpacking is that it's a good and quality item. I was especially pleased with the top – it fits comfortably and immediately feels like a familiar garment. As for the pants – they are also nice, but the cut is a bit unclear – it feels like more fabric is needed at the back. That is, they're long, there's plenty of space in the front for “the most important parts,” but at the back they're kind of “flat.” In general, if you have a fairly large “trunk,” they may slip and feel uncomfortable :) The length is fine. XXL will fit even if you're 190 cm tall.

I have no experience in this regard because I have never used any winter underwear. However, the time has come (my age caused it) that my knee area started to need extra warmth, so I had to decide on something and this set is enough for me. I don't feel like the material gets cold and unpleasant, maybe I'm an exception. I am satisfied.

WARNING I warn against buying this product, poorly made, like a canvas shopping bag but thinner, see-through, honestly the worst 100zl I've ever spent, I really feel sorry for US soldiers if they actually use this junk, it doesn't keep warmth at all, on the contrary, the material gets cold and unpleasant, the only reason I'm not returning it is because I rushed and tore off the tag too early. If I could give 0 stars, that's the rating this product would get because it doesn't even deserve one star.

This is already my third purchase in the store. The thermal underwear is of high quality, I managed to use it on the range. The purchase met all expectations. The store's service is, as always, excellent.

Very nice underwear. I recommend it.

Perfect for construction work and for everyday use. I recommend it.

Lightweight and well-fitted. There's nothing to complain about.

The size matches the description. The underwear meets expectations. I use it every day now and I am satisfied (I spend up to 9 hours outside) with the quality. I recommend it.
