Klunkerz refers to the progressive-thinking, fun-loving hippies who started the sport of mountain biking in the 60's and 70's, before mountain bikes were even mass produced. These messenger bags from PORTER pay tribute to the free-thinking cyclists and their design revolves around ultimate functionality. The exterior of the bags are made from 500D Cordura nylon with waterproof treatment on the outside and PU coating on the inside. Unlike conventional messenger bag designs, these bags can be closed by tightening up the drawstring on the main compartment. There are zipped pockets on the cover flap, left and right sides and the front compartment, offering ample storage solutions. Two versions were created, in black or beige colorways, which are available right now on the B Jirushi Yoshida online store for pre-order. Delivery will take place sometime later this month.
