Not good for racking gear
For me, the gear loops on the size small harness are definitely my biggest complaint. You can't rack much gear, forcing me to wear a chest gear loop more often than I would have liked, the loops in back are in an uncomfortable position to reach, which can be very frustrating at the wrong moments, and it does not pack down very well. I've worn other harnesses that do not have a problem accommodating four easily-accessible gear loops despite the smaller circumference. Now that the buckles on the leg loops are wearing through the webbing, I probably will never buy another Petzl harness. But, I have a feeling this is a problem unique to the smaller sizes.
