For size: For me as a 1.80m wide, very thin man bodysuit fits very well in size L. At the abdomen and pelvis, it is very large (for me), the sleeve could be a bit longer, but are acceptable. The patch pockets are optically about 5-10 cm high. Legs are perfect in length to. For processing: The fabric feels good, does not act cheap, the seams are also good. The zipper is made of plastic, very Grobzahnig and also makes a good impression. He is, however, the inside right "unloving" sewn on, which disturbs something if you do not t-shirt or camisole underneath.
