Helikon US LVL 1 Long Sleeve Thermal Shirt - Black

The Helikon-Tex long-sleeved thermal shirt in Black is intended to be worn directly against the skin. It acts as the foundational clothing layer in the U.S. Army’s ECWCS (Extended Cold Weather Clothing System). Constructed from lightweight and durable Helikon-Tex Quick Dry fabric, it effectively wicks moisture to keep you dry and comfortable.

Thermal Quick Dry material

The shirt is made from thermal knit fabric, Helikon-Tex Quick Dry, which is made entirely of polyester. The material dries rapidly and effectively wicks moisture away from the body, ensuring thermal comfort, even during intense physical activity. A specially designed fiber weave boosts evaporation efficiency. The garment integrates smoothly with additional layers of the ECWCS system or other thermal apparel, making it ideal for cold and transitional weather conditions.

Well-thought-out design

The long-sleeve shirt includes integrated thumb holes to prevent the sleeves from moving up during activity, delivering additional warmth to the hands. The back panel is extended to stop the shirt from riding up when crouching, providing enhanced protection for the lower back from the cold. Flat seams are used to minimize skin irritation, thereby improving comfort during wear.

Main features

  • made of thermal Quick Dry fabric
  • flat seams that minimize the risk of chafing
  • thumb holes in the sleeves
  • the fabric dries quickly and wicks away moisture
  • designed to be worn directly against the skin

    I bought it in my usual size and the sweater fit a bit snugly, but the seams under the arms were bothersome. They are made in a really strange and uncomfortable way there. And if you take a larger size, it will hang too loosely. The store accepted the return without any problems, and for that I am grateful.

    The undershirt has poorly fitted armhole cutouts and thumb holes in the sleeves. This is the first Helikon product that has disappointed me so much. The only advantage is the material. The product was returned.

    I bought it as something to wear underneath in winter; it doesn't have any thermal insulation, it's just a synthetic sweater. Also, I want to emphasize, I ordered size M—it's sized like an S, even though I'm quite slim and not tall.

    The seams under the armpits are sewn much too tightly, which significantly restricts freedom of movement. It really digs in, and this is not the case at all with the LVL2 product.

    It's decent, but I feel like it was sewn the wrong way – the side seams are quite unusual. For now I'll keep it, maybe I'll get used to it, but I probably wouldn't buy it again.

    I bought the thermal shirt for cycling and trekking. It does its job. Thermal clothing from Militaria made a good impression on me, so I bought a few different models. I recommend it.

    A very comfortable and pleasant to the touch shirt – works great both in the field and in the city as a first layer. If other colors were available, I would definitely buy another one.

    Very good shirt, great at wicking away moisture and helping to prevent sweating. The fitted material protects against wind getting under the shirt. It's comfortable to wear and doesn’t irritate the skin.

    I use this shirt for running and it really makes a difference. There's no need to wear many layers, just a longsleeve and a jacket. The sewn-in gloves are very practical. I recommend it!

    The military shirt in one color looks very good! Simple cut, durable material, and comfort of use. Even after many washes, it still looks like new. I recommend it!

    The shirt is aesthetic, pleasant to the touch, and breathable. For me, the downside is the thumb holes—at size M, when I put my thumbs through, the shirt pulls at my hand and gets tight. I don't personally use the holes, but someone else might find them useful. Despite that, I highly recommend it.

    I bought the Helikon US Lvl 1 Long Sleeve olive thermoactive shirt and I am very pleased with my purchase. The material is pleasant, lightweight, and effectively wicks away moisture, so comfort is maintained even during strenuous activity. The shirt fits the body well, doesn't squeeze, and the long sleeves protect against cold. Perfect as a first layer or for outdoor workouts. I recommend it!

    Very high-quality clothing, lightweight and comfortable thermal shirt, best worn directly on the body during long and demanding activities. Dries quickly, keeps you warm on cold days, and provides a cooling sensation in summer. The special polyester weave efficiently wicks moisture and increases evaporation area, so the skin stays dry. Ideal base layer under a uniform. This is a really great and worthwhile purchase – I recommend it.

    Excellent long-sleeve shirt, perfect for wearing under a shirt. This is my first purchase of this type, but definitely not my last. As usual from Helikon—I recommend it!
