One of the industry's first lumbar packs, the Day is known for its function-first design. After 40+ years in our line; we've revamped this classic built with Delta Wing Compression System and added more functionality for efficient storage on and off trail.

The original technical hiking lumbar pack marches on stronger than ever after 40+ years. Built with ultra-durable ripstop Nylon fabric, the Day lumbar pack is as comfortable as it is versatile.
