A constant curator and longtime admirer of its product line, lifestyle retailer kapok has partnered with modern luggage maker Haerfest to create the E13 Shell Backpack. Given the chance to develop its own backpack with the American-based brand, kapok chose its favorite E13 model and employed a navy canvas construction with tan nubuck cowhide and navy ghost PVC. This collaborative piece continues with an expandable, fully-lined main compartment and concealed double zip fastener. The semi-concealed front pocket and smaller interior zip pocket enhance the bag’s utility, making it practical as well as sleek. Furthermore, each adjustable strap provides Haerfest’s signature double brass ring and stud system for a rugged aesthetic. Limited to only 10, the kapok x Haerfest E13 Shell Backpack is currently available here as well as in store with a price tag of $3,300 HKD (approximately $425 USD).
