Does anyone have any experience with the lumbar style day packs? I've had multiple surgeries in each shoulder and they have been flaring up lately. It looks like this might be a good solution for day hikes that might ease the shoulders up for when I need to carry more weight on multi-day trips.
I could cut the necessary day trip stuff to water, a sawyer, snacks and a tiny first aid kit, etc...and be plenty light.
Are they comfy and stable or do they slide around your waist non-stop? Any tips or specific recommendations are appreciated!
