This is the most wonderful messenger bag I've ever used, and I'm really glad that I finally upgraded from the funky-but-inefficient canvas bags I've been living out of for ages. I use it daily, and also when I travel, and I love its functionality, durability, myriad pockets, and color. (Mine is Redwood, which is a little orange-y, and gorgeous.) The shoulder strap *is* long, but completely adjustable, and hasn't gotten in the way for me at all. I twice dropped it with my laptop in it, and the laptop is still fine. The only flaw I've found is that the waist strap (which I use on occasion) is thin, and would benefit from a either a bit of padding or just width around the hips.

I used this for a week long vacation and could fit everything that I needed (minus the bouldering gear) into my bag. I am now using it for classes and so far it has held up very well walking around campus. I have yet to try it on my bike. I love the waist belt, makes carrying the load a little easier since weight is dispersed to the hips. Shoulder cushion is sufficient it could be a little longer in length. My laptop (15.4") fits great and I am sure there is room for a 17".
So far it has been beyond convenient.

I love my new bag. It is a great size and fits "my life" inside it! I can carry my books, my water bottle, wallet, and laptop and then go to the grocery store and put in some produce and it doesn't get smooshed since the bag natuaraly holds it shape. The laptop pocket is a little small and doesn't fit my computer but I thought the bigger bag was way too big for my needs (plus it fits in the other pockets). The sholder strap is also excessively long which was easily fixed with some scissors and matches. I have had it for about a month and just yesterday discovered a new pocket, it is the bag that just keeps on giving! I also love the waist strap (the feature that I was specifically seeking) as I bike everywhere that I can. Overall this bag is delicious!
