I purchased this a few years ago but only used it a few times, so I'm selling it. Here's the manufacturer's page: Inspired by Adidas' rich heritage from the 70s, the "ARCHIVE_M1" is dedicated to the modern digital generation. In today's information-saturated society, it's a luxury to strip away the unnecessary and wear only what's essential. The "ARCHIVE_M1" was born from this concept.
