Had some Trainigsmatten and am glad to have finally found the "perfect" mat. No intensive plastic or chemical odor. The mass do not necessarily reflect the specified length. I have the length ordered 1.80, but only 1.75 long. Still 5 points. It is slip resistant and has a pleasant sun feeling. The mat has lt. Manufacturer with a reliable and permanent protection against bacteria and Pilzfbefall. It is easy to clean and does not show any deformation. And as already mentioned, the Airex is preferred by many professionals ... that also says something about the quality and robustness of the mat. Strong buy recommendation.
