I originally purchased the small but it was quickly apparent that they were too small for me. So I sent them back and got a medium which appears to be the right width for my chunky thighs but they are too long (I'm 5'2") and I have to keep hiking them up to keep the knee area in the right place. So, they're ok but I wouldn't recommend them if you are between sizes. Might be okay if you are tall and slender and in between sizes (ending up with a too short pant) but not the other way around.

I find myself in between sizes for harnesses: small waist, larger legs. While I like BD Alpine bod (easy to put on) the med is too large in the waist and the small too small in the legs. I tried the BD Vario but the rise was incredibly short.

I haven't used the Pandion but so far, I like what I see. The rise is good; it seems to fit me well. One reason I like the design is that it looks easy to go pee (using a freshette) without removing the harness. With my regular climbing harness it's awkward but doable but the extra layers when mountaineering makes the whole belay loop/dual tie in points cumbersome. This harness has the tie in up and the fly area clear.

The single gear loop is a downside but I mean to fix that. I originally thought that Petzl had a free floating gear loop which I thought was a cool idea (because I could position it where I want) but no matter that they fixed it with stitching. I intend to add more gear loops (but free floating). It may not work but I'm game to try. I just have to figure out how to have gear loops on the buckle side....

(four stars because only one gear loop)

This harness looked promising for mountaineering; the wide webbing looked more comfy than the alpine bod. I figured that with the tie in point as part of the waist belt would make it easier to go pee without removing the harness or fighting with the belay loop as I do with my regular harness (I use a freshette and sometimes the harness combined with clothing layers makes it challenging to use).

Unfortunately, the rise on this harness is practically non-existent so I returned it. Also, there is no way to undo the pre-threaded buckles so you always have to step into the harness.

I like the idea of this top as it is a nice change from the shelf bras but wish it was made for different cup sizes. I have a small ribcage but am busty so I got a medium to fit the ribcage. This holds me all together nicely but not attractively. From the reviews I had read of this top and related tops, I had hoped I would avoid the uniboob or at least have no skin on skin. A larger size may have helped with this but at the cost of support.
I found the shoulder straps to be very close to my neck. This is somewhat irritating as it rests on the muscles on either side of my neck and I was worried that it would lead to tension pain; fortunately this has not happened. Still, I would have preferred the straps to be a little further apart.
All that said, I do wear the top and found it comfortable enough to sleep with it on during an overnight ski trip. I believe that since this is a full-length top and provides over-all support, there is no bra-band constriction (which occurs with some sports bras).

Love the athletic fit, the pockets, the look. The fit in the torso is great. A minor issue: the sleeves are a bit too long (I'm 5'2" so I'm used to this somewhat). A more irritating issue is that the collar is too tall--I feel like I'm wearing a neck brace when I zip it up fully. That said, I'd buy it again.
