Hey there! I know a lot of women that like the fit and function of Osprey and Black Diamond packs. They’re a heavier than something like the Hyperlight, but they have more structure and many people find that they’re more comfortable for long trips (especially if you’re not used to carrying a heavy pack). Unless you’re doing a Denali Prep Course type trip I’d recommend tying to keep pack size down to 55-75 L.
A common issue for smaller women is finding a hip belt that can get snug enough to sit on your hip bones, but if you go to a good gear shop they should be able to help with fit.
Also worth considering what you’ll do after your course. What are a few of your top climbs and objectives? That will help guide your pack search.
