Review for model:

Size: XL

I have the T-shirt in size XL, and it fits perfectly. In the shoulders as well as at the waist. I am 190 cm tall and weigh about 100 kg. On the small Velcro patch on the shoulder, I have a blood group patch. The T-shirt is very comfortable and durable. When it gets sweaty, it dries quickly. I wash it by hand or at 30°C on a hand-wash cycle. I will buy it again when the time comes.

Size: L

The T-shirt is very high quality; this is not my first T-shirt from this line, and I definitely recommend it. It feels pleasant to the touch, wicks moisture effectively, and dries quickly. The size is accurate; at 183 cm and 85 kg, size L fits perfectly.

Size: XL

The T-shirt is solidly made, has an attractive cut, and fits the figure well. It gives the outfit a subtly military character while also going well with jeans. It dries quickly after washing. The pockets on the shoulders seem of little use, but the fabric is very pleasant to the touch.

Size: L

I like this T-shirt very much. I use it both for work and for walks or cycling. It is slightly thicker than typical running shirts, so during very hot weather it may turn out to be too warm. The material feels slightly rough to the touch, but I actually consider that a plus because it does not shift around on the body as much. The navy blue colour looks almost black and does not resemble a classic blue at all. I chose size L, and at 182 cm tall it fits me perfectly. It is a bit loose, but that is due to my slim build.

I definitely recommend it. The fabric is of good quality, feels pleasant to the touch, wicks moisture effectively, and dries quickly. The sizing is true to size; for a height of 176 cm, size L fits perfectly. It is great for longer outings and intense activity on warm days.

In my opinion, the Velcro on the sleeves is not a very successful or practical solution — personally, I would rather do without it. The shirt also feels somewhat heavy, especially considering its construction. I bought it only because I couldn’t find a better option on this site that met my requirements.

Size: L

The material is very good (soft on the inside), ideal for hiking. It dries quickly and wicks sweat away well. For a height of 178 cm, size L fitted well and it did not shrink in the wash.

Size: XXL

I am very satisfied. The shirt performed excellently in the mountains. Even on a steep climb, there was only a small sweat mark under the rucksack. That is truly impressive.

The shirt is very light and breathable, which makes it great for trekking, cycling, or working on warmer days. The material dries quickly and wicks moisture away quite effectively, while the looser fit provides excellent freedom of movement. The pockets and the hook-and-loop fastenings on the sleeves are also a plus — they are small additions, but they prove really practical in the field. It’s a very successful shirt for summer, although during more intense activity it may take on the characteristic odour of synthetic materials a little more quickly.

Size: M

Durable, very comfortable. I rode for several days in the bike park with a protector underneath it, and it fits so perfectly as if I wasn’t wearing one at all. I recommend it and I’m buying another one.

Review for model:

I bought it based on the reviews and the marketing that described this shirt as “thermoactive.” Right from the start, it felt artificial, almost plastic-like. In practice, especially in hot weather, it does not wick away sweat and provides almost no breathability at all — as if you were wearing cling film. It has very little in common with real moisture-wicking performance clothing. I also do not see any advantage over cheap products at a much lower price. It’s a shame that Helikon decided to release something like this.

With a summer like this year’s, a shirt like this, which dries quickly and feels cooler than a cotton one, works perfectly and will probably become the standard.

The T-shirt dries quickly, wicks sweat well, and also conducts heat well. Surprisingly comfortable considering it's completely synthetic; for me, it's absolutely comfortable. The velcro also does its job and is well made.

These T-shirts really don't need much recommendation. They are very breathable, quickly wick moisture away, which ensures fast drying and keeps your back feeling dry. Any odour is due to the use of synthetic fibres, but the decision is simple – you choose either dryness or a nice smell.

The thermoactive T-shirt works perfectly both during training and various outdoor activities. TopCool copes well with wicking away moisture, ensuring comfort even on warmer days. It is lightweight, dries quickly, and does not restrict freedom of movement. The cut of the T-shirt is comfortable and its workmanship is of a high standard – strong seams and durable material that does not lose colour or properties even after many washes. The olive colour looks attractive and fits well with both outdoor and military clothing.
