I have had this backpack for Fall, Winter, and Spring, and it is the perfect pack for these often wet months. I use this pack for field work when I often get caught out in the weather, and also need to put my pack down just about everywhere. It also makes a nice, dry seat in a pinch! This is a great, dry pack, and fits just about everything I need for a day's worth of work or adventuring. The one thing that makes this pack *almost* perfect is the front zipper. If the pack is not full then when you fold the top closed and buckle it, it creates a weird configuration for the pack fabric and the zipper becomes difficult to open and requires two hands and a little finagling. I also agree with another commenter here that some padding, or frame for the back would make this more comfortable. But alternatively, it is nice that it folds up really easily--and this feels like more of an intentional choice than a flaw like with the zipper.
