The t-shirt arrived great. The majority of the T-shirt is made of a material that is comfortable to wear. Unfortunately, ventilation is incorporated on both sides, for which a mesh material was used, which itself already scratches and was also sewn in with thick seams, which also scratch, so that I was convinced of the durability of the whole. Unfortunately, I can't confirm that with the T-Shirt. A good idea, which unfortunately was not thought through to the end with the claim of high wearing comfort.
