Size isn't on

    I got this harness to replace my petzl after it got to be to big, that can happen when you lose weight! I ordered it a little over a week ago, I ordered a M thinking it was going to do running on the small side judging what I read on reviews elsewhere. Its doesn't but I'm right in the edge of the small where it could be to small! I don't know if there is anyone else out there with this same problem, if so I'd like to know if you had the same problem! Other than the size issue it seems like a great, its only my second harness and my petzl was pretty old so not alot to compare it to. I love how light and simple it is tho, it packs down really small too!

    Judging from my other Arc harness, I'm not surprised. I am 'small' in most other climbing/alpine gear. In a SMALL Arc harness, I feel skinny. Even ice climbing with a bunch of layers, I am just within the limits for leftover tail on the waist strap.

    I'm looking at this for mountaineering...

    I'm looking at this for mountaineering with glacier travel with rappelling and steep to near vertical climbs. I'm hoping for some direction if this is the way to go- I like the lightweight and very packable (and one of the few AT products still made in Canada). I'd appreciate any feedback if anyone is using this or if I should be looking at something else. Thanks.
