The Mystery Ranch Kletterwerks Summit Backpack hearkens back to 1975. That’s the year that Mystery Ranch founder Dana Gleason II started up Kletterwerks, the name of his first endeavor designing and manufacturing backpacks. The Kletterwerks name has since been revived as a heritage collection that features minimalist designs perfect for everyday carry. A prime example is this Summit Daypack, made in the USA and featuring an incredibly durable 1000D Cordura shell with 1680 denier ballistic nylon reinforcement, resulting in a nearly indestructible build. Complementing the panel loading design is a front accessory pocket and padded 15″ laptop sleeve, along with YKK zippers and heirloom leather label and zipper pulls.
