With sleek functionality and a minimalist attitude, the ultralight Ozone harness is the go-to choice when it comes time for the redpoint burn. 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. We also added Speed Adjust waistbelt buckles for quick on/off and a breathable wicking liner for mid-summer cragging sessions.

Pre-threaded Speed Adjust waistbelt buckle
Bullhorn-shaped waist built with Kinetic Core Construction
4 pressure-molded gear loops
Adjustable, non-release elastic rear riser
Soft, breathable 3D mesh lining and abrasion-resistant shell

Gear Loops

Number of Gear Loops

Gear loops are used to hold gear (quickdraws, cams, etc) onto your harness. 4 gear loops is most common.

0 - 1 Gear Loops

Most often on full body harnesses or guide/gym style harnesses.

2-3 Gear Loops

Mostly found on lighter harnesses made for [ski] mountaineering or high-end sport climbing where weight is a high priority.

4 - 5 Gear Loops

The standard/most common number for climbing harnesses. Perfect for sport and trad.

More Than 6 Gear Loops

Designed for long multi-pitch and big wall climbing, found on harnesses made to hold the maximum amount of gear.

Worth Considering

Occasionally, the number of gear loops will change on a harness model depending on the size. There could be 7 gear loops for the med/large but only 5 gear loops for the xsmall/small. In this case we list the highest number for the filters, and then write an explanation on the product page like, “Size S/XS can only fit 5 gear loops.”

4 Gear loops
Ice Clip Slots

Ice Clip Slot

Ice clipper slots are made to fit a carabiner that holds ice screws. These slots are generally only used by ice climbers but there is no disadvantage to having them on your harness.

Less than 40% of harnesses will have ice clipper slots. And those harnesses will usually have 2 or 4 slots, often located next to, or between, the gear loops.

Haul Loop

Haul Loop

Trad climbers often look for a haul loop as they're intended to haul a rope (second line) or pack (while you climb the chimney).

A haul loop can also hold shoes or other accessories. Although not the intended use, it is also commonly used to hold a chalk bag.

Splitter Choss Gear Review no rating given just a review

Simply put, the Ozone rocks and surprised me greatly in its ability to be much more than a harness for sport climbing at Rifle. For 6 weeks, climbing trad and multi-pitch in Yosemite and the Sierras this past summer, I found it was the only harness I needed and definitely the only one I wanted to pack. Grab one of these and you too can enjoy the feel of a super sleek, sexy, lightweight climbing rig that will make you feel like you can float up the rock, or at the very least hang effectively like me.

Climbing Gear Reviews UK Performance 5/5 Quality 5/5 Value For Money 4/5

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.

Rock and Ice Gear Review rating 4/5

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.
