With sustainability becoming a major keyword today, upcycling and vintage fashion have been on the rise over the past few years — staying at the forefront of this market is Frankie Collective, which recently dropped a series of patchwork sweatpants. Following the first drop in late January, the Vancouver-based label has released a second round of the reworked range which sold out in a matter of hours.

As spotted on Frankie Collective’s website, the sweatpants are constructed using damaged sweaters from the likes of Tommy Hilfiger, Champion, adidas and Nike. Each piece is unique and made from 100 percent recycled material using three separate sweaters, with street-ready color combinations of deep green and white, orange and pink, beige and more. While all of the unisex designs are sold out, the brand has announced on its Instagram that its team is working on the next drop.

Keep your eyes peeled for Frankie Collective’s third drop of vintage reworked sweatpants over at the official web store.
