Great pack, I already have the Farpoint 40 and just bought the 55 for more versatility in travel. Men's pack is really unisex in our experience. The women's is slightly smaller, different coloring, and slightly tweaked ergonomics. Technically not carryon size, but most people don't have a problem with it if removing the daypack (YMMV).
