Heat 3Way Briefcase

The Porter-Yoshida & Co. Heat 3Way Briefcase impresses with a clever carrying system that adapts as a briefcase, backpack or shoulder bag, offering flexibility for a variety of daily situations. The bag presents a look that mirrors material engineering: Japanese-made, high-abrasion nylon and tarpaulin fabrics meet a resilient, water-repellent design influenced by military aesthetics. Inside, a thoughtfully organised layout with specialised compartments accommodates a laptop as well as your mobile essentials. In the classic black colourway the exterior remains deliberately understated, while the contrasting textures accentuate the premium nature of the piece. Quality details such as precise bindings and reinforced stitching–combined with Japanese craftsmanship–provide the foundation for a long-lasting companion in professional life or travel. For those who prioritise uncompromising durability, urban elegance and intelligent features, this briefcase-backpack hybrid offers real value: design and performance in one.
