The reviewer found the K4’s full-size frame better suited to backcountry hiking than climbing, scrambling, or rocky vertical terrain. The reviewer found loading cargo between the K4’s frame and bag considerably easier and faster than with the K3. The K4’s organization includes a central cavity, hydration compartment, long side zipper pockets, and open side pockets.
The reviewer found the angled K4 bottle holder easy to reach while worn and unobtrusive to natural arm movement. The K4’s specialized lumbar pad and waist belt transfer most of a heavy load to the hips, according to the reviewer.
Reported strengths
