My purpose in buying it was to use it alone on short hikes and with a pack on longer ones and camping. I see a benefit in not having to take my pack off to get at items that I use on the trail. And if I have to ditch my pack, my survival kit and first aid kit is still with me.
You said it exactly right Aloha. Its no use to have all your stuff in your backpack if you take your backpack off when you get to camp and walk around 'naked', that's the whole point of EDC, the %'s are higher you will need something from it when your on the trail.
Glad you posted this, its something i can keep looking at for the future.
