The undershirt or tank top from Huber should certainly convince everyone because of its good fit. It is long enough cut to be worn as an undershirt can without slipping out of his pants, but can be worn as a tank top in summer. The shirt is through the material at closely - that you should consider when buying. To size - otherwise I have size 40 - here I got 42 and would say the shirt is a bit smaller, so you should think maybe to order two sizes to try on. The material fässt per se, like a thin swimsuit - even you should know. I think it's not bad, in its composition, but my stuff is not easy. I had it as an undershirt on and have worked in the garden, at 20 ° C - as you already notice that you start to sweat and his shirt nothing passes. After all the material in the fresh air dries very quickly again, but I'll probably still stay again in the future in cotton / elastane blends.
Overall a nice shirt if you like the material. From the fit and cut from there by myself but not "complain" about.
