bought in October 2014. As soon as you wear first, broke up the seam on a pair of trousers. nahch 2 months as equal to the second hose - although I hardly wear the pants. why I wear them almost? because the "function" of these pants completely disappoint. when I sweat pants suck just like normal cotton underpants. then when you touched these briefs, they are inside and out equally wet (ie as cotton trousers). In October I had functional underpants of Odlo and bought Under Armour. the pants of both brands see (despite frequent wear) not only still like new, probes are also functional underpants tatseachlich. 1 prefer pants odlo or armor than 2 or 3 or more of these here, both the durability, appearance and above all also feature.
