An upgraded version of our popular High Coast Foldsack, now with added volume and enhanced functionality. High Coast Pro Foldsack is a lightweight, durable and versatile daypack made from ARCTEN fabric. Its fold-over closure lets you expand the volume of the main compartment, and small items can be stored in the spacious front or side pockets – or in the detachable external pocket that can be converted into a crossbody bag. Durable, practical and comfortable, this is a backpack built to last for many years.
