Founder and designer Takeshi Osumi still manages to tread the fine line between streetwear and fashion with his brand, PHENOMENON. They have collaborated with PORTER on several items this season; however, these backpacks show a different face of the progressive label. From glen check to neon colors, there is a model that would suit most styles. On the inside, the bag is equipped with a laptop compartment, alongside additional storage space on the front and sides. All items are in stock at PHENOMENON dealers internationally and can be purchased through their new online shop on ZOZOTOWN.
