Too much happiness. The fit is very comfortable, very cosy, very warm, and wicks away sweat very quickly. Skating at 70km/h and -5°C on the ice rink – you don’t feel a thing! Truly an excellent product. I’d definitely recommend it!

Helikon US LVL 2 Base Layer Set - Olive Green
The Olive Green Helikon-Tex thermal underwear set, consisting of long-sleeved top and leggings, is designed as a second layer of clothing in the ECWCS (Extended Cold Weather Clothing System) used by the U.S. Armed Forces. Made from lightweight and durable Comfort Dry fleece, the set efficiently wicks moisture away from the body while providing insulation. The addition of elastane gives the fabric flexibility and ensures unrestricted movement.
Thermoactive Comfort Dry fleece
The underwear set is made from Comfort Dry thermal fleece, composed of 95% polyester and 5% elastane. The fabric dries quickly and efficiently wicks moisture away from the skin, ensuring thermal comfort even during high-intensity activity. A grid-like weave structure increases the evaporation surface, while the fleece fibers provide excellent insulation in cold conditions. The set integrates well with other layers of the ECWCS system or other thermal clothing, making it ideal for cold and transitional weather.
Well thought-out cut, high collar
The shirt includes long sleeves with thumb openings that help keep them in place during movement and offer added warmth around the hands. An extended back panel helps protect the lower back and kidney area from cold, especially while bending or crouching. Flat seams are used to reduce skin irritation. The high collar guards the neck against wind and cold, while the long front zipper makes the shirt easy to put on and provides ventilation when needed.
Fitted leggings
The leggings are fitted with elastic bands at the waist and ankles, ensuring a snug fit and helping retain body warmth. The fabric and cut allow for unrestricted movement. A traditional fly is included for practicality. Flat seams help reduce the chance of chafing and skin irritation.

Very comfortable set, providing comfort. Combined with level 1, it is ideal under a jacket for winter evenings. The quality matches the price. I am 183 cm tall, 74 kg in weight – size L is appropriate, neither too tight nor too loose.
-
This underwear protects very well against cold and wicks moisture thanks to the special structure of the material. In winter I wear it while active, and in spring and autumn when I plan to stay still for a long time or sleep outdoors.
-
I'm 187 cm tall, wear XL and even low temperatures don't bother me – with such underwear you could even wish for frost. Wearing it is pure pleasure. The zip doesn't bother me at all, maybe I'm just less sensitive.
-
The underwear fulfils its task perfectly. It is warm, pleasant, and moisture is efficiently wicked away. For now, I don't see any drawbacks, time will tell how durable this set is.
-
The underwear set is very warm. It works as insulation under uniform trousers and as pyjamas. Handles even -10°C. It is thicker and warmer than LVL1. It is well made and does not rip.
-
The Helikon US LVL 2 thermoactive underwear is a great choice for colder days. The light and quick-drying material retains heat well and wicks moisture to the outside. The thoughtful cut and flat seams make it very comfortable to wear and it doesn’t cause chafing. The extended back of the shirt additionally protects the back. It's a reliable set for those who value comfort and functionality in demanding conditions.
-
The set works great both during outdoor activities and for everyday use. It retains heat even at -8°C, and at the same time, it's reasonably priced, offering a good alternative to standard sets.
-
The underwear is very warm, comfortable and pleasant to the touch. It provides high comfort even at -10°C when worn under a uniform and jacket. The price reflects the high quality and properties of the product. I definitely recommend it.
-
The thermal underwear is warm and comfortable. The size comes up a bit larger than standard. At 187 cm and 93 kg, an L would be appropriate. The material is pleasant to the touch, the fastening protects the neck, and the zip has an extra cover.
-
Compared to my previous, non-branded set, Helikon comes out brilliantly. It keeps a very good temperature and comfort of wearing. I recommend to everyone.
-
The underwear set is very warm, pleasant and definitely thicker and warmer than Helikon's LVL 1. Although you can wear it over LVL 1, such a combination would probably only be suitable in extreme cold. I haven't had a chance to fully test it yet, but I'm sure it will perform excellently during frosty nights in a tent. Solid workmanship, well-thought-out solutions, and a price that matches. I highly recommend it.
-
Review after about three months of use. Size corresponds to the table, material is pleasant to the touch. I wear it as LVL 2. It works well in changing weather thanks to the zipped collar. Provides thermal comfort and freedom of movement. There are no unpleasant odours after exercise, and it dries quickly after unzipping the collar. Very good value for money. I recommend it.
-
Compliance with the description confirmed. The underwear is very warm, ideal for working outdoors throughout a winter day. It's so comfortable you can easily forget you’re wearing it. Size also matches the table.
-
I am very satisfied with the purchase. As for the size, L fits me perfectly, although I usually wear L/XL size clothes. The product looks solid, and the elastic band in the trousers holds well.
