A harness is the one piece of climbing gear that's attached to you on every single roped climb. It needs to be safe, but it also needs to be comfortable enough that you forget you're wearing it, whether that's a 20-minute gym lap or a long day at the crag.
This guide walks through how to choose a climbing harness, what the features actually mean, and how to check the fit.
Start with how you'll climb
Most climbers don't need a different harness for every discipline. A good all-round harness covers gym climbing, sport climbing and most day trips outdoors. But it helps to think about where you'll spend most of your time:
| Type of climbing | What to look for |
|---|---|
| Gym and sport | Comfortable padding, easy adjustment, a few gear loops. Lightweight options are popular for hard sport climbing |
| Trad and multi-pitch | More gear loops, supportive padding for hanging belays, comfortable all day |
| Beginner all-rounder | Adjustable leg loops, simple buckles, comfortable fit that grows with you |
| Industrial and arborist | A different category with different standards. See our industrial range and speak to us about your requirements |
Getting the right fit
Fit matters more than any other feature. A harness that doesn't fit properly is uncomfortable at best and unsafe at worst. Check these key points:
4-point harness fit check
Too low and it can slip down when you hang or fall
Firm, but you can still breathe and move
Adjustable loops help if you climb in layers
Ideally with a rope in a gym or shop. Check nothing digs in or slides
Always follow the manufacturer's instructions for threading and doubling back buckles, and have an experienced climber check your set-up if you're new.
Features that matter
Padding and comfort
More padding is generally more comfortable for hanging and falling, while minimalist harnesses are lighter and pack smaller. If you're often belaying, working routes or climbing multi-pitch, comfort is worth paying for.
Adjustable or fixed leg loops
Adjustable leg loops let you add or remove layers and fit a wider range of body shapes. Fixed leg loops are lighter, but need a precise fit.
Buckle type
Many modern harnesses use quick-adjust buckles that are easy to set up, while others use a traditional double-back system. Whichever you choose, make sure you understand exactly how to buckle it correctly before leaving the ground.
Gear loops
Gym climbers can manage with a couple of loops. Sport climbers typically want enough to rack a set of quickdraws, and trad climbers need more room for protection. Rigid loops are easier to clip, and some harnesses also include a haul loop for trailing a rope.
Women-specific and unisex fits
Many brands offer harnesses designed around different body proportions, with different waist-to-leg ratios. They're not essential, but if a unisex harness isn't sitting well, try a design cut for your body shape.
Common mistakes to avoid
- Buying on colour or price alone. A harness you never feel comfortable in is a harness you won't want to wear.
- Choosing the wrong size. Check the manufacturer's size chart and measure your waist and thighs rather than guessing from clothing size.
- Ignoring the age of second-hand gear. Harnesses wear out over time and you can't see all the damage. See our guide on when to retire your climbing gear.
- Not asking for help. Everyone's body is different, and it can take a few tries to find the right one.
As Sophie often says: it took a few harnesses before she found one that really fit, and it was worth the search. Don't be afraid to ask questions before you buy.
