5525Gallery's collaborations with fellow countrymen Porter continue to be some of our favorite co-branded projects to emerge from Japan. For the launch of its pop-up space inside Tokyo retailer UNITED ARROWS & SONS, 5525Gallery has once again worked with the storied luggage brand on a gorgeous, timeless range of heavy black leather bags.

Included in the lineup are a backpack, waist bag, two tote bags and our favorite, a large saddle bag. All pieces feature heavy-duty tumbled leather bodies and gold hardware.

The overall result is a fantastic, premium range of daily travel companions. You can pick up the full collection now from UNITED ARROWS & SONS in Japan.
