I ordered two, but I plan on grabbing more at another time. These hangers work as intended. As backpackers buying from a backpacking company, we all likely know what our packs weigh, so staying within the weight limit for these hangers is pretty easy.
I tried posting a photo for the review, but upon trying to post one photo I'd gotten an error stating the upload took too long and I should upload only one at a time. (the upload was only taking about 2 seconds to reach 99% completion before the error and was indeed only one photo)
Anyway, each of my packs are in the range of 10-15 lbs that I have hanging from these hangers and I have zero concerns about the hangers failing.
These are dense and sturdy little tools that keeps the backpacking gear obsession stay organized. I started with two just to see if I would like them first and I do - so I'll definitely be grabbing more down the road.
I did need to cinch the shoulder straps tight to be able to hang the packs, but beyond that, while they are not difficult to take off the hangers, accidentally knocking packs off of them is not likely. Possible? Of course - it's a hanger, but you'd have to be pretty gruff to make that happen.
The one thing I'd note is making sure the rack or dowel used to hang the packs is capable of holding the weight of the packs.
But now my gear closet has packs that are ready for adventure that are easy to grab and go. No more digging through the pile of packs at the bottom of the closet to grab the one I'm looking for.
