Designed to keep you comfortable while clipping bolts and climbing difficult routes, the Black Diamond Ozone harness is optimized for serious sport climbing.

• Kinetic Core Construction™ (KC²) employs a tri-laminate of liquid crystal polymer (LCP) strands that are distributed along the horizontal axis of the harness belt
• LCP strands are sandwiched between lightweight taffeta and layered with polyethylene foam inserts; a durable nylon shell and a soft, breathable lining complete the design
• KC² eliminates bulk and distributes the load evenly throughout the harness, offering excellent comfort while working routes
• Bullhorn-shaped waistbelt is ergonomically designed for all-day comfort
• Lightweight aluminum Speed Adjust buckle is pre-threaded for quick and secure 1-handed operation
• 2 pressure-molded polyethylene gear loops are reinforced with nylon webbing to provide excellent racking space with high strength
• Rear elastic straps feature low-profile metal buckles that adjust easily; buckles slot into a sleeve to keep them seated and protect the elastic
