This isn’t a new trend by any means, but lately I’ve noticed a lot people in the backcountry carrying bear spray in the side pouches of their packs. This is really, really foolish and is basically the same as not bringing it at all.
If you’re unfortunate enough to get into a situation where you need to use your bear spray, you’ve got to have it out at a moment’s notice. Bears can run unbelievably fast, and there will not be time to go rooting through your pack.
I’ve seen a few people attach it to the shoulder straps of their packs, and while this is an improvement over the side pouch method, its still not ideal because you could potentially become separated from your pack, and thus from your bear spray. Myself, I like to use a carabiner to clip my bear spray onto one of my belt loops so its always handy, and also easily adjustable if for whatever reason I need to rearrange things.
Bottom line is if you’re going out into the bush, not only should you be carrying non-expired bear spray that you know how to use, it should be within reach at all times. Better safe than mauled folks.
