Big Gun Harness - Black Diamond

18 June 2019
Awesome. Safety focused. Durable. Comfortable and thoughtful design. Climb Nowra

average to good harness

14 May 2014
Good comfort all day sitting on hanging belays on MP but not as good as other big wall harnesses I tried before. Handy to have extra loops for trad gear and double belay loop. The down side: based on the size calculator on BD website I purchased an X-Large only to find out is too large and now using it tighten to the very end (and still would tighten it further more if I could). 3.5 stars

great comfy gear hauling harness

good harness for hanging around & hauling gear. only downside is the difficulty of getting all the buckles done up properly. otherwise, love it

Super Comfy

No more pain on hanging belays with this harness - I've sat for ages on long multi pitches in this and never felt a thing. Lots of gear loops also makes it convenient for racking trad gear. Awesome harness.

Comfortable and plenty of gear loops

Such a great harness! I wear this harness daily for hours on end. Sometimes I'm just standing in it, but often I'm hanging and climbing in it. the large easy to use gear loops are such a help, and the double belay loops are so amazing! Is a heavier harness due to its size, but the comfort is worth the weight to me.
