Review: Black Diamond Ozone Harness

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.
