This thing is a comfortable tank! It's heavy. If you're looking to go lightweight, this is not where you need to be looking. However, if you're looking for a solid, well made pack with all of the bells and whistles, this is it. I prefer to use mine when I'm packing bulkier loads in colder weather or when I know it will be days before I can resupply.
The pack carries great. I have lighter packs that save weight, but this one really manages the load well. I've carried 60 lbs in this pack more comfortably than 25 lbs in lighter packs.
The suspension is highly adjustable and offers lots of options. The hydration access works well. A cover is actually included and attached. The pockets and compartments also allow you to load your pack in all sorts of different ways while still retaining access. I really hate the weight penalty, but I love the stability and comfort.
