Too much happiness. The cut is very comfortable, it's very cozy, very warm, and it wicks sweat very quickly. The rides in the courier at 70 km/h and -5°C are not even felt! An excellent thing. I definitely recommend it!
Helikon US LVL 2 Black thermal underwear - set
The black thermal underwear set from Helikon-Tex, which includes a long-sleeved top and leggings, serves as a secondary clothing layer within the ECWCS (Extended Cold Weather Clothing System) utilized by the U.S. Armed Forces. Crafted from lightweight yet durable Comfort Dry fleece, this set effectively draws moisture away from the skin while offering warmth. The incorporation of elastane enhances fabric flexibility and ensures ease of movement.
Thermoactive Comfort Dry fleece
The underwear set is crafted from Comfort Dry thermal fleece, consisting of 95% polyester and 5% elastane. The fabric dries rapidly and efficiently draws moisture away from the skin, ensuring warmth even during intense activities. A grid-like weave structure enhances the evaporation area, while the fleece fibers deliver superior insulation in cold environments. The set seamlessly integrates with other layers of the ECWCS system or other thermal garments, making it perfect for cold and transitional seasons.
Well thought-out cut, high collar
The shirt features long sleeves equipped with thumb openings to secure them during movement and provide extra warmth around the hands. An extended back panel shields the lower back and kidney area from the cold, particularly when bending or crouching. Flat seams are incorporated to minimize skin irritation. The high collar offers protection for the neck against wind and chill, and the long front zipper facilitates easy donning and allows for ventilation as needed.
Fitted leggings
The leggings are designed with elastic bands at the waist and ankles to ensure a snug fit and maintain body warmth. The fabric and cut offer freedom of movement. A traditional fly is included for convenience. Flat seams minimize the risk of chafing and skin irritation.

Very comfortable set, providing comfort. Combined with level 1, perfect under a jacket for winter evenings. Quality matches the price. I am 183 cm tall, weigh 74 kg – size L is suitable, not too tight or loose.
-
This underwear protects very well against the cold and efficiently wicks away moisture thanks to the special structure of the material. I wear it during movement in winter, and in spring and autumn when I plan to remain still for a long time or sleep outdoors.
-
I am 187 cm tall, wear XL, and even low temperatures don't bother me – with this underwear you can even wish for frost. Wearing it is pure joy. The zipper doesn't bother me at all, maybe I'm just less sensitive.
-
The underwear fulfills its purpose perfectly. It's warm, pleasant, and moisture is effectively wicked away. So far, I haven't noticed any flaws; time will tell how durable this set will be.
-
The underwear set is very warm. It works well as insulation under uniform pants and as pajamas. It holds up even at -10°C. It is thicker and warmer than LVL1. Well made and does not unravel.
-
Helikon US LVL 2 thermal underwear is a great choice for colder days. The lightweight and quick-drying material retains warmth well and wicks moisture to the outside. Thoughtful design and flat seams make it very comfortable and prevent chafing. The extended back of the shirt additionally protects the back. This is 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 keeps you warm even at -8°C, and the price is reasonable, making it 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 matches the high quality and properties of the product. Definitely recommend it.
-
The thermal underwear is warm and comfortable. The size runs a bit larger than standard. At 187 cm tall and 93 kg, L would be suitable. The material is pleasant to the touch, the fastening protects the neck, and the zipper has extra coverage.
-
Compared to my previous, non-branded set, Helikon is amazing. It maintains a very good temperature and comfort of wear. I recommend it to everyone.
-
The underwear set is very warm, pleasant, and definitely thicker and warmer than Helikon LVL 1. Although you can wear it over LVL 1, that combination probably only makes sense in extreme cold. So far, conditions haven't allowed for full testing, but I am sure it will perform excellently on frosty nights in a tent. Well-made, smart solutions, and a reasonable price. I highly recommend it.
-
Opinion after about three months of use. The size matches the chart, the material is pleasant to the touch. I wear it as LVL 2. It works well in changing weather thanks to the zip collar. It provides thermal comfort and freedom of movement. After exercise, there are no unpleasant odors, and after unzipping the collar, it dries quickly. Very good value for money. I recommend it.
-
Compliance with the description confirmed. The underwear is very warm, perfect for working outdoors all winter day. It's so comfortable you can easily forget you're wearing it. The size is also as per the chart.
-
I'm very pleased with the purchase. Regarding sizing, L fits me perfectly, even though I usually wear L/XL. The product looks solid, and the pants' band holds well.
