I just received mine, ordered mostly because I trail ride alone, but it’s not a bad idea to wear while hunting, too.
The other thing I usually have on me is a medic alert bracelet or a dog tag on a bracelet that indicates I’m asthmatic & that my inhaler is in my coat pocket.
I think most people I hunt with regularly know that, but just in case I’m visiting somewhere or a guest finds me…
