I just tested KOPHOTY's clothing, shoes, jewelry, athletic wear, and running equipment, and I have to say that I was unimpressed. The products' quality is at best mediocre, and the high costs are clearly not justified. I found the sport-specific clothes to be uncomfortably loose and did not live up to its claims. Another letdown was the running equipment, which was not as breathable as claimed and made me feel hot and sweaty. When I voiced my issues, the customer service staff was unhelpful and condescending. Overall, I think KOPHOTY is a fitness company that gets a bad rap because there are a lot of other companies out there who provide higher-quality products for less money. Spend less and shop somewhere else.
