I bought this shirt as an option to pair with the Helikon MCDU combat shirt, and after the very first impression I can already say that the Vanguard represents a higher level of quality. This also applies to the material and wearing comfort — it seems more breathable than the MCDU model. At this point, however, I still do not have enough experience with the Vanguard while wearing a vest and additional gear. There is only one thing that surprised me a little: the color of the functional part. The sleeves and collar in the RAL shade are flawless and meet the standard, but the panel on the chest and abdomen is noticeably lighter than in the manufacturer's photos, almost tending toward a sandy color. This is not a big problem for me, but a darker shade — like the one in the promotional materials — would look better and be less conspicuous. For comparison, I am also attaching a photo: on the right side is the Vanguard shirt, and on the left are the Helikon MCDU trousers, more precisely their elastic section at the waist and back. In my opinion, the whole thing would look much better if the functional part of the Vanguard shirt were closer in color to RAL instead of having such a sandy tone. In my opinion, the price-to-quality ratio deserves a solid 4, maybe even 4.5, with a reasonable price being around 2000; above that amount, you are already starting to pay for brands like UFPRO. It should also be remembered that this is a combat shirt, so it is not fully universal and to some extent remains consumable clothing. Size L fits well for a height of 197 cm, although arm length is an individual matter, so I would treat this information as approximate. I also think that the sizing of the shirts and, in general, the upper garments is the same as in the case of Helikon.
