I’m extremely disappointed with Knox underwear. These are the most expensive underwear I have ever purchased, yet they have lasted the least amount of time. All of the seams on my underwear have fallen apart, despite washing them carefully according to the label's instructions. The seams are held together with an awful glue that simply doesn’t hold up, which is unacceptable given the high price point. I had enough pairs to get me through a full cycle, wearing at least two pairs a day (with proper ones for night as well), so each pair was only worn about once a month. Despite this minimal use, they did not hold up. For the price, I expected much better durability and quality. Unfortunately, I will not be purchasing from Knox again.
