Looking around for lightweight day hike options, I see that SAM has a 24" Industrial model that "meets the new ANSI Z308.1-2015 standard for a class B first aid kit.". It sounds like a short cut to meet some arbitrary workplace checkbox, rather than a viable option. I really don't see a scenario where 24" will work. Am I wrong here? I'd love to cut back on size/weight, but not at the expense of performance.
