Lifestyle retailer Kapok has teamed up with modern luggage maker Haerfest to create the E13 Shell Backpack. Kapok’s self-expressed ‘favorite’ from the Haerfest line, this backpack features navy canvas with tan nubuck cowhide and finished with navy ghost PVC. This collaborative piece continues with an expandable, fully lined main compartment and concealed double zip fastener. Each adjustable strap is finished with Haerfest’s signature double brass ring and stud system for more unique appearance. Limited to only 10 pieces, the kapok x Haerfest E13 Shell Backpack is currently available at Kapok.
