I bought these twice.  Once in 2016 and once in 2017.  I tried 3 different brands and these were my favorite.  I read people saying they don't hold up. I wear them exclusively at my full time job and they have worn in similar to a pair of blue jeans.  They are very soft now but nothing has ripped or broken.  I am buying more today as they are starting to get thin.  I figure each has about 2000 hours wear on them.  I really like these.
