OspreyTempest 30 Women's Hiking Pack

What season is this rucksack as changes were made early 2022

Will this fit as Ryanair carry on if the straps are tightened?

I’m going to peru for a 12 day trip. the rucksack will be my luggage. i’m trying to choose between 30l or 40l. i’d be interested in recommendations.

Does this come with rain cover?
