Hi Lily, I currently have the Xenon 85. I bought it because I'm planning on several long expedition climbs. I used it last summer on Rainier, and I will be returning it. I love Osprey packs, but the Xenon (Xena) series seems to be very sloppy/floppy in regards to load carrying. The attributes that make it a great large pack are also its downfall in terms of stability. I'm looking for a different pack now, either a different Osprey series, or maybe another brand. Something that has a slightly more rigid form. One of the other women on the climb had the Gregory Deva 60 and she loved it. I'm looking at the Deva 70 now.
