Super Comfy - Super Adjustable

I love this harness, it's got a good level of adjustability so it fits just right.
Really like the colour too and it has just the right amount gear loops for a trad climbing rack

comfortable adjustable harness

Overall I find this one of the more more comfortable harnesses I have been in and it is the most adjustable I have owned. My weight fluctuates enough that having a more adjustable harness just makes sense for me. It would probably be my perfect harness if it had a few more gear loops.
