A defining philosophy of Japanese luggage specialists Porter-Yoshida & Co. is that “bags are tools”, with functionality and convenience always taking precedence over decoration. The MONOCHROME series distils this ethos into an innovative range of multipurpose bags designed for everyday adaptability.

This 25-litre backpack draws inspiration from traditional military packs, combining rugged practicality with thoughtful updates for modern life. Key features include a large main compartment with a drawstring closure and buckled flap for weatherproofing, along with a padded rear compartment designed to fit a 16” laptop. The main body is built from water-resistant three-layer nylon taffeta, with a waterproof tarpaulin base to keep tech and valuables safe and dry, while the back panel is constructed from “Cubic Eye®” piqué fabric. This highly breathable, quick-drying honeycomb material is designed to reduce heat and sweat buildup while adding cushioned comfort for the wearer. Combined with other features including shock-absorbing shoulder straps and a military-inspired MOLLE system, this is a highly versatile pack for carrying larger loads both in day-to-day life or on your wider adventures.
