Choose a harness certified to EN 12277 and UIAA 105, sized so the waist belt sits snugly above the hip bones and the leg loops are snug without pinching. Gym and sport harnesses are light with few gear loops; trad harnesses add padding and four or more gear loops; alpine harnesses have adjustable leg loops for layers. Inspect the belay loop and tie-in points every time, and retire per the maker.
A harness connects you to the rope. Fit and condition are non-negotiable.

- Hang in it at the gym to check comfort.
- Double-back or tie-in points as the maker specifies.
Inspect every time
Belay loop, tie-in points, buckles and stitching. Retire if worn, cut, fused or exposed to chemicals.

Add a climbing helmet. Browse ropes and protection.
Common questions
How should a climbing harness fit?
The waist belt snug above the hip bones so it cannot slide over them, and leg loops snug with room for a flat hand.
What certification should a harness have?
EN 12277 and UIAA 105 are the standards for sit harnesses.
How long does a climbing harness last?
Follow the maker's lifespan guidance. Retire it sooner if the belay loop or tie-in points show wear or damage.
Do I need adjustable leg loops?
They help for alpine and ice climbing over bulky layers. Fixed leg loops are lighter and simpler for sport.
