My wife has recently bought an Osprey Skimmer 28. She loves the pack but the ventilation and the pocketing system are inferior as compared to Osprey Sirrus models. I believe the Sirrus is the highest class model for the women's Osprey backpacks.
For instance, the Sirrus has a better ventilation...
I just bumped into this thread and I also have an Osprey - Stratos 50. An excellent model. As for the guarantee, luckily I haven't used it yet but I've heard legends about it (in a positive sense). So I am happy that you guys are all confirming it. :)
