Retrovelo took the Swiss military’s classic bicycle frame bag and updated it to fit today’s laptops and other necessities for the corporate warrior.
It’s made of vegetable-dyed and anilin tanned 2mm thick leather and attaches to standard frames with a horizontal top tube. Available in black or brown, dimensions are 35.5x12x30cm (LxWxH). Its two compartments flop over the top tube and clip together then around your seat tube to keep it from swaying back and forth.
