    Black Diamond Ozone Rock Climbing Harness - The Ozone Climbing Harness by Black Diamond is a one of a kind harness offering sleek functionality with a minimalist attitude. The sport-minded Ozone’s streamlined yet comfortable design is built with Kinetic Core Construction, which uses thin strands of Vectran along the entire harness structure to evenly distribute load and eliminate the need for bulky foam padding. With Speed Adjust waistbelt buckles for quick on/off and a breathable wicking liner for mid-summer cragging sessions, the ultralight Ozone harness is the go-to choice when it comes time for the redpoint burn. If you are looking for something that is radical in design, minimal in weight and optimized for serious sport climbing, you have found it with the Ozone Climbing Harness by Black Diamond.

    This is my forth or fifth harness so far and I love it. I recently just upgraded/retired my petzl corax and this is definitely more comfortable. This is my first harness with the unadjustable leg loops, but I am pleasantly surprised. I have big bikers legs, so a skinny legged person may not like the leg loops. I am 6'4" 185 lbs and got the large, fits great with plenty of room for me to get fat with, or for layering.




    My first harness is the Black Diamond Chaos in medium. It fit fairly well and was super comfortable when I first got it but I started losing weight as I continued to climb. The medium size became too large so I picked up the Ozone in size small. It's a tight fit but it's incredibly light weight. Perfect for indoor sport climbs where you don't need a million loops and want something that's fairly comfortable and light. I have noticed that the padding is a little stiffer than the Chaos but I believe over time it'll soften up. Currently, this is my go-to harness for indoor routes and it's way cheaper than the Chaos. The only other thing preventing a full 5 star review is that Black Diamond has some funky sizes. Wish they made something in between a small and a medium.
