Rating: rated 4.5 of 5 stars

I've been climbing in the Big Gun harness for a little over a year now. I used to hang in it for about 8 hours a day, most weekdays, at my old job. It did incredibly well for distributing weight so my back wasn't killing me.

My ONE complaint (and it is actually a big complaint) is that it needs TWO waist buckles so that the gear loops and bullhorn waist belt are centered. As it is, everything is offset, and you have to shift your harness whenever you stop hanging and start climbing again.

Just got done with the first climbs using the BD Big Gun. I tired on several harnesses after my Metolius finally started showing signs of wear. The Arc'Teryx proved to be very light by may cause broken ribs if you take a screamer.

These harnesses are at very opposite extremes and I was somewhat suspect of the mobility of the Big Gun until I climbed with it. For all the padding the Big Gun does well on sport climbs and the gear loops are amazing for setting up your rack and very comfy two.

This is not a sport cragers ideal harness but if you're looking to spending time on multi-pitch trad routes I would definitely recommend the Big Gun for its comfort, durability, and organization.
