An all-around adjustable harness can adapt to body shape and clothing layers; an alpine model can prioritize low weight and donning with skis or crampons on. Petzl's CORAX and ALTITUDE show those design choices, but compare exact size ranges, fit and instructions before choosing.
Harnesses are built around different movement and gear needs. These maker-published examples show two common decision paths.
Compare the design choices
| Example | Maker-published features | When to compare this style |
|---|---|---|
| Petzl CORAX | Adjustable waist and leg loops; Petzl lists gym, crag and multi-pitch use | When fit flexibility and clothing layers matter |
| Petzl ALTITUDE | 150 g in size S/M, two gear loops, designed for mountaineering and ski touring; can be donned with skis or crampons on | When low bulk and alpine transitions matter |
These are examples, not universal categories. Gear-loop layout, sizing and adjustment vary by model.
Fit the model before comparing features
A harness must fit according to its own instructions. Check the exact size range, waist and leg-loop adjustment, tie-in points and buckles. Standards and inspection are covered in our climbing harness fit guide.
A climbing helmet is part of the same equipment decision; see our helmet construction comparison. Browse ropes and protection.
Common questions
What is an alpine climbing harness?
It is designed for mountaineering or ski touring. Petzl says its ALTITUDE can be donned while wearing skis or crampons and weighs 150 g in size S/M.
Are adjustable leg loops useful?
They can help accommodate clothing layers and different body shapes. Check how the exact model adjusts and fits.
Can I use an alpine harness for sport climbing?
Follow the model's intended use, certification, fit and gear-carrying information; do not assume one harness design suits every climbing style.
Which harness should I choose?
Prioritize a correct fit and the intended activity, then compare weight, adjustment, gear loops and how it works over your clothing.
