      Comments about Big Gun Harness:

      I bought this harness to use at the gym and for outdoor sport climbing. I haven't had a chance to use it for big wall stuff yet. It is rather comfortable once you adjust it properly and it's easy on you when you take big falls leading. I cannot comment on long-term durability just yet (it's been a few months), but it seems very well constructed throughout.

        Comments about Big Gun Harness:

        This harness is truly fantastic. I bought it with an eye towards big walls and long trad climbs, but it really performs amazing well on sport climbs. There is no reason that it has to be miserable when you fall repeatedly on the crux of a sport route and spend awhile hanging. Bottom line - if you have a lot of gear or think there is a decent chance of falling, this harness is highly recommended - even much nicer for belaying someone who you know is going to fall, or who you are going to have to lower.
