The plain mesh cap on the right, made by ZETT, is size O, which is 59-60cm. I've used it once and washed it, but it's still in good condition. It's almost like new. The Basic Ench on the left is originally soft, so it shows some signs of wear. I've actually worn this one about 5-6 times, so the price is around ¥500. The types of hats might be completely different, but both look good(^^)
