Review topics: [].
"I normally wear large size clothing, but after reading other reviews I ordered the XL. I could barely get it on at 6'2" and 215 lbs. Wearing anything other loose fitting shorts underneath it will not be possible. The legs are tight around the calfs."
"The proportions are weird. Legs and arms are tight and height top to bottom doesn’t seem to be cut for a human being. Tried size medium and large. Really wants to like these but can’t even get them on. Oh well."
"Way too tight"
"Since XL was out of stock i ordered L (I'm 185cm, 75kg) so thought it would fit perfectly, but the arms and legs are too tight, feels more like M size. Otherwise it is good quality for the price."
"If you’re looking for slim fit, this is it . Personally I’d prefer a MUCH looser fit"
"Der Anzug ist kuschelweich, super bequem, passt perfekt und versprüht gute Laune. Ich möchte ihn gar nicht mehr ausziehen !!"
"Gute Qualität und tolle Passform, trägt sich sehr angenehm."
"Die Qualität ist jetzt nicht die beste"
