I used it this winter at work, so I already have some observations. For work where you know there will be a lot of movement, it's a bit poorly breathable, which ends up making you sweat, and it's made of material that isn't necessarily pleasant to wear when it's wet. As the name suggests, I would treat this as a second layer, and in the fall, you can use it as a softshell if you have bought a size larger. If you put some long-sleeve merino underneath, you'll have a really solid layer on you. For outdoor work, I would rather choose wool, but for camping where there isn't as much movement, it works great.

The Helikon-Tex US LVL 2 Black thermal underwear set is of excellent quality. In winter, when there was no electricity or heating, it effectively protected me from the cold in the apartment. I definitely recommend this product.

I bought them for overnight stays during cold, winter nights while camping at -3°C and they kept me warm in my sleeping bag. They are extremely comfortable, and with my weight of 100 kg, size 3XL is just right.

Helikon US LVL 2 Olive Green thermal underwear set - what is Helikon stays Helikon. Great set. Really warm. In my case, at 180 cm height and 85 kg weight, I had to change the pants to size M and the top to size L, and it fits fine.

A big plus for the quality of workmanship. Combined with the first layer, the thermal comfort is at a good level. It retains heat very well and wicks away sweat excellently. A great purchase.

The best underwear you can buy here on the site, I already own 2 sets. It will be the warmest when combined with LVL1. The size matches the size chart. After a long period of intensive use, I can say that it does not pill.

Extremely comfortable jacket, excellent cut, very warm and effectively wicks away moisture. While rollerblading at 70 km/h and -5°C, I didn't feel cold. Excellent product, highly recommended!

Comfortable set, very cozy. Together with level 1 it goes perfectly under a jacket on cold winter evenings. The quality matches its price. I'm 183 cm tall and weigh 74 kg, size L is suitable for me—not very tight, but not very loose either.

This underwear is a great thing. It retains body heat very well and the waffle structure makes sweat moisture more effectively wicked away outside. I wear it during activity in winter and in spring or autumn if I need to stay still or sleep outdoors.

187cm - XL and you don't know what frost is, you can even start wishing for frost ;) It's as if you've installed a set of radiators around you. Pure pleasure to wear. I don't complain about the zipper, probably because I have thick skin :)

Works excellently. Warm and pleasant. Wicks away moisture very well. We'll see how long this set lasts over time, so far there's nothing to complain about.

Very warm underwear set. Tested both in training conditions as a liner under uniform trousers and as pajamas. Works well at temperatures around -10 degrees. Thicker and warmer than LVL1. Solid workmanship means nothing comes apart.

Helikon US LVL 2 thermal underwear is an excellent choice for chilly days. Its light, quick-drying material effectively retains warmth while wicking moisture out. Thanks to the well-thought-out design and flat seams, it's comfortable to wear, with no risk of chafing. The longer back of the shirt provides extra protection for the lower back. It's a reliable set for those who value comfort and functionality in tough conditions.

The whole set works exceptionally well both in the field and for everyday use. It retains heat at temperatures down to -8°C, which combined with its low price makes it a good alternative to other popular sets of this type.

Very warm, comfortable and pleasant for the skin. No problem, you can feel comfort and warmth at -10°C wearing a uniform and jacket. The price for the quality of the product and its features is very affordable. I highly recommend it.
