Two criticisms I have yet:
Very resistant fabric seems not to be, because, according to the manufacturer's recommendation, he is at 30, not even to wash 40 degrees. Disappointing for underwear.
Worse is the sewn label: It is truly in XXL size and quite carelessly, in a pair of underpants even sewn on little unclean. It disturbs and scratching something. Sensitive people will spoil the fun to the underpants thoroughly! Personally, I have my shirt pulled back a little deeper into the underpants, the federal government considers it very well there in position, and thus solved the problem.
Conclusion: The pants like and fits very well with me, but for 5 star one would especially the label smaller and cleaner, less disruptive to install.
