This is one tough little pack! Enough room for an over-nighter or multiday if you pack small without the extra weight. It is well made and very comfortable. I love the waterproof zipper side access pocket, great to get to things you want quickly without unpacking everything. I almost gave it a four because my gear for a 3 day 3 season hike really fills it up but that is not the packs fault so it gets a five. I do tend to carry more than I need.
