On longer climbing sessions I like to keep my cell phone close by, but most of the time I have no backpack with me. So I would like to pack the cell phone in a little case that I can put on my climbing harness via a carabiner.
I know some case manufactures that do provide durable small cases, but none with a loop to put your carabiner through.
As it can get pretty rough in the wall, I like this box being durable since it needs to protect my stuff.
What box does work well and has proven to withstand harsh conditions?
Consider that I do not want to wear clothes with pockets.
