It's easy to put on without removing your skis or crampons, making it a practical solution. It’s also modular, with removable padding in the waistbelt and leg loops, so you can adapt the level of comfort and weight. Gear loops and ice screw retainers allow you to keep your gear within reach.

Gear LoopsNumber of Gear LoopsGear loops are used to hold gear (quickdraws, cams, etc) onto your harness. 4 gear loops is most common. 
0 - 1 Gear LoopsMost often on full body harnesses or guide/gym style harnesses. 2-3 Gear LoopsMostly found on lighter harnesses made for [ski] mountaineering or high-end sport climbing where weight is a high priority. 4 - 5 Gear LoopsThe standard/most common number for climbing harnesses. Perfect for sport and trad. More Than 6 Gear LoopsDesigned for long multi-pitch and big wall climbing, found on harnesses made to hold the maximum amount of gear. Worth ConsideringOccasionally, the number of gear loops will change on a harness model depending on the size. There could be 7 gear loops for the med/large but only 5 gear loops for the xsmall/small. In this case we list the highest number for the filters, and then write an explanation on the product page like, “Size S/XS can only fit 5 gear loops.” | 2 Gear loops |
Ice Clip SlotsIce Clip SlotIce clipper slots are made to fit a carabiner that holds ice screws. These slots are generally only used by ice climbers but there is no disadvantage to having them on your harness. 
Less than 40% of harnesses will have ice clipper slots. And those harnesses will usually have 2 or 4 slots, often located next to, or between, the gear loops. | No |

Haul LoopHaul LoopTrad climbers often look for a haul loop as they're intended to haul a rope (second line) or pack (while you climb the chimney). 
A haul loop can also hold shoes or other accessories. Although not the intended use, it is also commonly used to hold a chalk bag. | No |

I found the Petzl Fly harness ideal for glacier travel and splitboarding. I can’t speak to more advanced or alpine intentions yet, but for my intended use, the Fly will continue to be my go-to harness. It’s comfortable, light, and you pretty much forget that you’re wearing it while skinning, booting, and riding. Then, add in the sweet packability and the fact that you can put on the harness with skis or board on. Score.

A pictoral representation of UIAA-105 and EN-12277 standards for harnesses.
The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
