Choosing a climbing harness: a buyer's guide

A harness is the piece of kit you trust with your weight every time you leave the ground, so it pays to get it right rather than grabbing the cheapest one on the rack. The good news is that any harness sold by a reputable brand is certified and strong enough to hold a fall. The real decisions are about fit, comfort and matching the harness to the kind of climbing you actually do.

Fit comes first, always

No spec sheet matters if the harness does not fit you. There are two things to get right.

• The waistbelt should sit snugly above your hips, not slung around them. You want it tight enough that it cannot slide down over your hips when weighted, but not so tight it digs in. Most harnesses adjust at the waist, so try it done up with a couple of inches of tail spare.
• The leg loops should be comfortable when you sit back into them, with enough room to layer up in winter but no excess slack. Some harnesses have fixed leg loops, which are lighter and simpler; others have adjustable leg loops, which suit big swings in clothing thickness or anyone between sizes.

The honest test is to hang in it. Many shops have a spot where you can sit back on a rope and load the harness for a minute. If it pinches, rides up, or puts pressure on a sharp point, keep looking. Comfort is not a luxury here — it is what lets you stay relaxed at a belay or while working a route.

Match it to your climbing

Once it fits, the deciding factor is use. The difference between harnesses is mostly padding, weight and how much gear they can carry.

• Gym and sport climbing: you carry little more than a few quickdraws, so fewer gear loops and lighter padding are fine. Something like the Black Diamond Momentum is a popular value all-rounder that handles gym and sport without fuss, while the Black Diamond Solution is a well-liked, more comfortable all-around and sport option.
• Trad and multipitch: you hang in the harness for longer and carry a full rack, so you want more padding and more, stiffer gear loops to organise cams, nuts and slings. The Petzl Adjama (men's) and Petzl Luna (women's) are well-regarded adjustable all-rounders that cover everything from sport up to multipitch comfortably.
• On a budget or just starting: the CAMP Energy is a recognised budget and beginner choice. If you are unsure you will stick with the sport, there is no shame in starting simple and upgrading once you know what you climb.

Count the gear loops: four is plenty for sport, while trad climbers usually want more and stiffer ones that hold their shape so gear is easy to grab. Think about padding too — more padding is plush for hanging belays but adds bulk and warmth you may not want indoors.

Safety, care and when to retire it

Buying the harness is the easy part. Using it safely is the job that never ends.

• Always do a buddy check. Before every climb, you and your partner confirm the waistbelt is doubled back (if the brand requires it), the belay loop is threaded correctly and you are tied in or clipped through the right points. This habit catches the mistakes that hurt people.
• Inspect it regularly. Look at the webbing, the tie-in points and the belay loop. Any fraying, cuts, faded or fuzzy webbing, or stiffness is a reason to scrutinise it closely.
• Retire it when needed. Take a harness out of service if the webbing is frayed or damaged, if it has caught a major fall, or simply with age and heavy use. Nylon degrades over time even in storage, so an old harness that has lived in a hot car boot deserves suspicion regardless of how it looks.

The takeaway: try several on, hang in them, and buy for the climbing you do most rather than the climbing you aspire to. A harness that fits and matches your discipline will be safer and far more pleasant than a pricier one that does not. Then build the buddy check into your routine so it becomes automatic — that, more than any model choice, is what keeps you safe.
