My vote: None ( 4.8 avg )


Ice routes in Canmore. Sport climbs in Rodellar. Splitters at Indian Creek. For those who climb it all, all year long, the Black Diamond Aspect provides four-season performance and comfort with our Dual Core XP Construction™. Dual Core XP features a waistbelt with two thin bands of webbing around the outside of the frame and an EVA foam insert to evenly distribute load without pressure points. The Aspect is designed with 4 Ice Clipper slots to accommodate your tools and screws, plus 4 pressure-molded gear loops and a 12 kN-rated haul loop. We also added pre-threaded Forged Speed Adjust buckles on the waistbelt and leg loops (to accommodate varying layers through the seasons) and Bombshell abrasion patches (which are 20 times more durable than standard nylon).

If there are differences in weight (due to multiple sizes or optional accessories) we'll list them here.

The default weight is the middle-most size, often this is size M.

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.

Outdoor Gear Lab Gear Review rating 3/5

The Black Diamond Aspect is a comfortable, four-season, all-purpose climbing harness designed to tackle everything from tough bolted lines to tricky pin-scarred routes, and even winter ice. A wide and thick swami belt and equally large leg loops make this one of the more comfortable free climbing harnesses we've tested. It's more comfortable than the company's Chaos, but less comfortable than the Big Gun. Downsides: a one-inch gap between the two gear loops makes it harder to access gear on the rear loop and the comfortable foam makes the harness a bit bulky when packed. We choose lighter, more compact harnesses for half-day or longer approaches. But, on the whole, this is a good quality, relatively inexpensive, all-purpose harness. For $80 it offers well-rounded climbers a single harness for a reasonable price.

The Alpine Start Gear Review no rating given just a review

The harness has four ice-clipper slots, however, two are on the side, and two are located towards the front, over the leading edge of the forward-most gear loop. When the waistbelt is snugged up, these two forward ice clippers lie directly over the upper thigh. Even without screws, I find ice clippers in this spot annoying during more acrobatic mixed moves. Add screws, whose teeth love to snag pant fabric with even the slightest leg movement, and you’ve got an annoying, sharp mess to deal with.

Climbing Gear Reviews UK Performance 4/5 Versality 4/5 Value 4/5

So in conclusion I think Black Diamond have created a good all-round harness that would be suitable for most of you climbing adventures. My preference has been to use it for rock climbing for which it has been brilliant. I found it a little lacking for UK winter climbing (where more kit is needed) but perfectly fine for ice fall climbing.
I feel that it could be improved by trying to add some ventilation at the back and ditching the front ice clipper slots. Both minor points really so a great harness that’s well worth the price.

Climbing Gear Review

Trying to get your gear room under control? Try a single harness that does it all. The Aspect is comfortable enough for working a route or belaying at a hanging station, light enough (14 oz.) for fairly serious sending, and tricked out for ice and alpine routes. “The waistbelt fit without pinching, even when I was hangdogging on my first mixed routes,” reported one tester after a winter trip to Utah’s Provo Canyon. Black Diamond uses two thin bands of webbing on the perimeter of its waistbelt and leg loops to distribute load, and EVA foam to dissipate pressure. The Aspect has four molded gear loops (plus a bonus gear loop in the back), four slots for ice screw carabiners, and a burly haul loop tested to 12kN. A pre-threaded waist buckle and leg-loop buckles accommodate a range of clothing layers— and reduce possible user error. Testers’ conclusion: “Rugged and versatile.”

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
