Good quick use slings for being alone in Grizz country

[TheObserver]

Hey guys,

I use a safari sling on some of my rifles, and this allows me to have hands free all the time and it is really quick to shoot a rifle. There good but can make the neck/shoulder sore after hours/all day and not sure how well they'll do with a large pack (backpack hunting).

The one I am looking for would be more for shotguns, but don't see why it couldn't hold rifles too, I seen a really nice one on a thread but can't remember which one the guy was up north hunting Moose and it was a defense shotgun kind of hard to explain how it was but the butt was down by his hips and it came a little out from his body the barrel going up.

This sling would just need to allow me to fire a shotgun fast hip or shouldered at a potential charging Bear and the gun hanging hands free.

What do you guys use for something like this in Grizz country? Hope that is a clear enough explanation
