My experience with this pack so far has been wonderful. It is an average daypack size (28L) so do not expect it to be too big. The Wandrin is extremely comfortable and has been with me on many day hikes including some two day hikes. You can pack that thing with as much crap as you want but it will let you know when it has had enough. The waiste bands are comfortable as well the overall frame. Easy to use and fun to carry!
First of, one of the most comfortable packs I've worn, very form fitting and easy on the back. I like to cram a whole bunch of things into small places, so its perfect because no matter how heavy it gets, its a small pack with a very nice hip belt. Currently, I'm using it as a pack for textbooks as well as day trips, overnights, and a climbing pack, so I think its fair to say its very versatile. Only problem I can find is the main compartment is not nearly as wide as the picture makes it out to be.
