Ozone
Description
Steep jughauls, technical slabs or vertical pockets—when it comes to sport climbing, Black Diamond built the Black Diamond Ozone Harness to take on the full spectrum of bolt-protected challenges. Featuring our Kinetic Core Construction, which uses a thin layer of Vectran fibers in place of traditional webbing to evenly distribute weight across the waist and legs, the Ozone provides a comfortable yet minimalist fit for hangdogging and hard redpointing alike. Four pressure-molded gear loops hold enough drops for rope-stretching pitches, and the Forged Speed Adjust waistbelt buckle makes for super-fast on and off.

This harness is very comfortable considering how light and compact it is. Surprisingly, a few testers found the women's version, the Aura, more comfortable than the Black Diamond Chaos, which is beefier, more expensive and is supposed to be more comfortable. It could be that our testers (all men) fit better in women's harnesses. Who knew? At any rate, we were pleasantly surprised at how well it fit. Despite having only two gear loops, it was possible to fit a ton of draws because the gear loops are so big.
This harness forgoes traditional webbing for the internal structure and instead uses Vectran fibers. This adds stability to the shape of the waistbelt and leg loops; it was comfortable even when one tester hung for 15 minutes to analyze moves. Packability was top-notch, with the Ozone scrunching down to slightly smaller than a 32-ounce Nalgene bottle. Testers were able to use it for trad climbing, but preferred to rack on a gear sling instead of the gear loops. More than a few pounds on the harness caused discomfort and made it feel like the waistbelt was sliding down.
Buy this harness if you want a lightweight harness to take you to the next level on your sport climbing quest. It is well made, reasonably comfortable, swallows large numbers of quickdraws and won’t feel restrictive when you’re climbing in it. It is also fine for trad climbing on shorter stuff as well as sessions on the wall.
Conventional wisdom suggests that more padding, a wider swami and adjustable leg loops yield a more comfortable harness. But that’s not always true. I’ve climbed in dozens of harnesses from quilted big wall rigs to alpine g-strings and often the simplest designs are the most comfortable. That’s the case with Black Diamond’s Ozone. Streamlined, light as a snowflake and functional, the Ozone is marketed as a sport harness, but I’m using it for all types of rock climbing from cragging to multipitch trad. The Ozone is built with Kinetic Core Construction, a process where strands of Vectran (a strong, stable fiber used in spacesuits, ropes, and pro bike tires) are woven through the harness to help distribute load. The result is a light and comfortable harness without bulky padding to jab your side fat on high steps. I’d recommend the Ozone for sport climbs and trad routes where you’re carrying a single set of cams and nuts. I recently used it on the Rainbow Wall in Red Rocks, for example. On the downside: The Ozone could use a drop seat for mid-route, multi-pitch emergencies.
