The Black Diamond Ozone is a premium sport climbing harness featuring a lightweight breathable construction, fixed abrasion resistant leg loops, a ‘speed adjust‘ waist belt buckle and 4 pressure moulded gear loops. From Catalunya to Chamonix, we’ve been putting the Ozone through it’s paces in a variety of conditions and climbing styles to see how it performed.
Comfort & Fit
The Ozone is a supple and slightly padded harnesses that forms well to the contours of your body, the harness is comfortable during climbing, falling and hanging – the 3 food groups. I’m not sure if it’s just my shape – but on most harnesses the belay loops always seem too small (often pulling the leg loops into my man bits and dragging the waist belt down) – not in this case though, seriously I can’t stress enough how happy I am to find a long belay loop on a harness – if you also suffer from small belay loop syndrome (SBLS) it’s worth checking the Ozone out just for that feature, thank you Black Diamond.
Left: Multi-Pitch & Hanging Belays
On a single pitch, most harnesses will do the job without going to blue in the face (or other areas) – with that in mind, we took the Ozone up Via Smoking (Terradets, Spain… On a side note, a really excellent route) which involved a couple of hanging belays over 7 pitches of swinging leads.
Baring in mind the Ozone is a lightweight Sport harness, it performed very well and remained reasonably comfortable during long belays – eventually the waist and leg belts did begin to dig in and required some shuffling around but overall the Ozone is definitely a contender for longer routes when going fast and light.
Black Diamond have added some nice touches to the Ozone that make it fairly durable (especially considering it’s lightweight construction). The outside of the leg loops have a protective rubber rand (an area that seems to get scuffed through general use) as well as good quality stitching and a tough finish. As the Ozone has became the ‘go-to’ harness, it’s had a massive amount of use over the last few months and is ageing very well so far.
Sensible amount of gear loops, check. Fixed leg loops, check. Haul loop – missing (we’ll come to that). The Ozone has pretty much everything we’d want from a Sport Climbing harness, it’s 4 gear loops hold a good amount of gear – enough for a day out multi-pitch – whilst the simple design means it’s quick to slip on and off. The only thing we missed was a small rear haul loop – among other things I do like to clip my chalk bag onto the rear haul loop (I know you shouldn’t do this), it would be nice to see a small lightweight loop at the rear.
A Sport Climbing harness doesn’t need to be anything more then this – the Ozone is lightweight, comfortable and tough – we loved it, not to mention the generous belay loop (finally!) and the speed this thing goes on and off. It holds enough gear for long Sport routes and it wouldn’t be ridiculous to take it Alpine, Trad. or Multi Pitch climbing. Overall a fantastic harness.
