Don't pick a harness by color or because your climbing partner has the same one. What matters is how you'll use it: gym, sport climbing, alpine or a bit of everything. Then come leg loops, gear loops, weight and, above all, fit. We picked eight harnesses that cover everything from your first day at the gym to long multi-pitch routes. Prices from Spanish/European stores on October 5, 2026.
How we compared
- Use: gym, sport, alpine or all-around.
- Adjustable leg loops (layers, multi-pitch) or fixed (lighter and simpler).
- Gear loops: 2 are enough at the gym; 4 for routes with quickdraws or a rack.
- Weight and padding: fewer grams for performance, more foam for long hangs.
- Real waist and thigh size, ratings and price.

Gym, sport, alpine or all-around
A gym harness is simple: few buckles, 2 gear loops and a wide size range. The Simond First Klimb is the example: the maker limits it to top roping in the gym and does not recommend it for lead climbing.
A sport harness is about low weight and freedom of movement: fixed or elastic leg loops and 4 rigid gear loops so you can grab draws fast. The Simond Edge weighs under 300 g.
For alpine climbing you want adjustable leg loops (to wear over thick pants or with crampons), a haul loop and ice clipper slots.
The all-around harness is what most people buy: adjustable, comfortable to hang in and good for the gym, crag and via ferrata. The Petzl Corax, Black Diamond Momentum, Mammut 4 Slide and Salewa Xplorer fit here.
Adjustable or fixed leg loops
Adjustable leg loops with buckles fit any thigh and winter layers. They are the safe pick for a first harness or a shared one.
Fixed or elastic leg loops are lighter and have no buckles to loosen, but they only work if your thigh fits the size. They are more comfortable for summer sport climbing.
Gear loops and weight
Top roping at the gym, you carry almost no gear: 2 gear loops are enough. To lead outdoors you need 4, ideally rigid ones up front so you can clip draws without looking.
The gap between 300 and 500 g barely shows on a sport route. It shows more on long approaches and alpine days. If you hang a lot (belaying, multi-pitch), favor padding over weight.
How to get the size right
Measure your waist above the hips, where the waistbelt sits, and your thigh at its widest point. Check each brand's size chart: there is no universal sizing.
The waistbelt must sit above your hip bones and not slide down when you pull on it. If you are between sizes and climb in heavy layers, go up only if the leg loops are adjustable.

Verdict
If you only top rope at the gym, the Simond First Klimb does the job for €42. For a full first harness, the Simond Klimb at €50 is hard to beat. For a name-brand all-arounder, the Black Diamond Momentum is the lightest and the Petzl Corax the most comfortable. For alpine days and heavy layers, the Mammut 4 Slide. And if you already lead hard routes, the Simond Edge weighs under 300 g.
Frequently asked questions
What size climbing harness do I need?
Measure your waist above the hips and your thigh at its widest point, then check each brand's chart. The waistbelt should sit above your hip bones.
How often should you replace a climbing harness?
It depends on use. Makers usually give a maximum life of about 10 years unused, and far less with heavy use. Replace it sooner if the belay loop shows its wear indicator, the webbing is cut or it took a severe fall.
Adjustable or fixed leg loops?
Adjustable for a first harness, winter climbing or alpine routes. Fixed if you want low weight for sport climbing and your thigh fits the size well.
Can I use a climbing harness for via ferrata?
Yes, a certified climbing harness works for via ferrata. You also need a dedicated via ferrata energy-absorbing lanyard.
