The latest from reputable Japanese manufacturer Yoshida & Co. is the PORTER Regista Messenger Bag.
The PORTER Regista Messenger Bag is a part of the brand's Regista line, which puts a focus on practicality over style. From a distance the pack looks fairly plain, but a closer look will reveal a diamond ripstop finish, which gives it more of a textured look; more importantly, however, it protects the bag from strenuous use. The PVC coating provides further protection from water and the nylon material makes it breathable. The interior has several compartments for small items while the larger areas will fit most traveling essentials.
The Regista line certainly lives up to the concept of practicality. It's the ideal bag for those who plan on using it for the long term.
