Definitely not thermal! This is a man made fibre base layer which is very breathable so good for warm weather. I used it as a base layer for a 6 day motorcycle trip in temps 4 to 17 degrees c and it wasn't enough. On the warmer days it was excellent, very breathable and light. The long sleeves can tuck into my under gloves. I like the fit & very comfortable material. The thumb loops are dud, unfortunately. They do cut into the hand making them sore, but I'll be warm washing and stretching the sleeves to see what gives. Overall, worth the money.

The T-shirt is made of high-quality materials. I wear it every day to work, both at temperatures from 4 to -21 degrees, and it always performs great. It is comfortable, loose, and does not restrict movement.

Happy with the quality of this shirt I haven't used it for its intended purpose but rather just while sleeping in my sleeping bag and it's been very comfortable.

Happy with the quality of this shirt I haven't used it for its intended purpose but rather just while sleeping in my sleeping bag and its been very comfortable.

I chose the size according to the chart and the jumper fit snugly on the body, but the seams under the armpits were uncomfortable. It's very strange and inconvenient how they're made there. If you take a bigger size, it will hang too loosely. The shop accepted the return without any problems and I appreciate that.

The undershirt has poorly fitted armholes 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 has been returned.

I bought it as something to wear underneath in winter, it doesn't have any thermal insulation, it's just a synthetic jumper. Also, I'd like to point out that I ordered size M – it's actually like an S, even though I'm quite slim and not tall.

The seams under the armpits are sewn much too tightly, so freedom of movement is significantly restricted. It really digs in and this isn't the case at all with the LVL2 product.

It's okay, but I have the impression that it was sewn inside out – the side seams are rather unusual. For now, I'll keep it, maybe I'll get used to it, but I probably won't buy it again.

I bought the thermal shirt with cycling and trekking in mind. It serves its purpose. The thermal clothing from Militaria made a good impression on me, so I bought several different models. I recommend it.

Very comfortable and pleasant to the touch T-shirt – works great both outdoors and in the city as a first layer. If other colours were available, I would definitely buy another one.

Very good T-shirt, wicks moisture away excellently and helps prevent sweating. The fitted material protects against letting wind under the shirt. It's pleasant to wear and doesn't irritate the skin.

I use this shirt for running and it really makes a difference. No need to dress in many layers, a long sleeve and a jacket are enough. The built-in gloves are very practical. I recommend it!

Military T-shirt in one colour looks very good! Simple cut, durable material and comfortable to wear. Even after many washes it looks like new. I recommend!

The shirt is stylish, pleasant to the touch and breathable. For me, the downside is the thumbholes – in size M, when I put my thumbs through, the shirt pulls at my hand and feels tight. Personally, I don't use the holes, but they might be useful for someone else. Despite this, I highly recommend it.
