For indoor lead and top-rope, a comfortable all-round harness with adjustable leg loops is ideal. Padded waist and legs help on hanging belays and when projecting.

How to choose a climbing harness
A harness is the piece of gear you'll wear on every climb, so fit and comfort matter as much as the technical specs. This guide covers the key criteria to consider, advice by level, and the most common mistakes to avoid.
Key criteria
- Fit and adjustability: A harness must sit snugly on the hips, not the waist. Try it on loaded — sit into it and check there's no pressure on your hip bones. Adjustable leg loops are a real asset if you climb in different layers across seasons.
- Buckle system: Most modern harnesses use auto-locking or double-back buckles. Check how many points are adjustable: some models only adjust the waist, others adjust waist and both leg loops independently, which makes a significant difference for an accurate fit.
- Padding: Thicker padding increases comfort during long hangs and rest sessions, but adds weight. For short gym sessions, minimal padding is fine; for multi-pitch or long sport routes, more padding pays off.
- Gear loops: Count and placement matter if you plan to carry gear. Gym and sport climbers can manage with two or three loops; trad or alpine use typically calls for four.
- Weight: Relevant mainly if you're hiking to the crag or doing alpine routes. For pure gym climbing, weight is rarely a deciding factor.
Advice by level
- Beginners: Prioritise fit and ease of use over features. A harness with a straightforward buckle system and good adjustability will serve you longer as your body adapts to climbing. Avoid buying purely on price — a poorly fitted harness is uncomfortable and potentially unsafe.
- Intermediate climbers: You likely know your preferred discipline now. Sport climbers can look for a balance between comfort and low weight. If you're moving into trad, check you have enough gear loops and that the belay loop is robust for frequent device use.
- Experienced climbers: Choose based on the specific demands of your target routes — ultralight for alpine objectives, maximally padded for big-wall or long sport routes.
Common mistakes to avoid
- Buying without trying: Harness sizing varies significantly between brands. Never buy based on size alone — always check the manufacturer's waist and leg measurements against your own.
- Ignoring seasonal fit: If you climb outdoors year-round, a harness that fits perfectly over a t-shirt may be too tight in winter with a shell jacket. Look for models with wide adjustment ranges.
- Neglecting inspection: Harnesses degrade over time, especially with UV exposure and repeated falls. Check stitching, webbing, and belay loop regularly, and follow the manufacturer's retirement guidelines.
