Mountain Hardwear Enterprise Backpack - 21L

Comfortable, good organization. No waist belt which I LIKE for a school and travel pack.

It meets every expectation -- including color (green). I couldn't be more satisfied (tho my wife doesn't like the color -- says it will be too easily identified)!!

I've taken this to work for the past two weeks or so now, and it's holding up well. Enough space for a 15" laptop in the sleeve if you need it, otherwise the sleeve works well as an organizer between papers and the rest of your stuff. Main compartment can hold specialty-size paper if you need it; I've hauled multiple sets of B4-size paper, and even some 11x17 if you leave enough space for it to lie from bottom front to top back of the pack. The built-in organization works well for a few pens, pencils, and a calendar or two. The front compartment is a little awkward, as the pocket goes all the way to the bottom of the pack, so it's tough to operate with one hand if you're you're trying to get to something quick. The top mini-pocket works well for office ID's and zip drives, and is thin enough for the NFC to work on badged doors if you don't want to pull your ID out of your backpack. The water bottle pockets unfortunately have the same problems that other backpacks have, in that they will dig into the main compartment if they're full. That was kind of expected, though, and I only use them for small items like a raincover and assorted odds and ends. I haven't tried it for business travel yet, but I could see it working well for overnighters.

4/5 just because the zipper could be better if it extended all the way down to the bottom, and getting a laptop or large items in and out of the pack is a little more awkward than it should be. 100% still functional though. Great to have a professional-looking backpack with all the features one expects from an outdoor company, especially the sternum strap. Doesn't look out of place when you're going in for a meeting!

I bought this bag to replace my Marmot messenger bag as a daily commuting bag, as I am now carrying my laptop and riding on the train. The bag has plenty of room for the laptop, coffee/water bottle, lunch and random other necessities. The bag is also extremely light weight, its compact and the shoulder straps are very comfortable; it even held up in the rain. The only negative (and reason for the 4 star rating instead of 5), is that there could be more internal organization pockets, but there are certainly enough to carry the essentials.

The backpack is comfortable, but I am returning it for one pretty important design flaw - the water bottle pockets! They are spacious and having 2 is great, but the problem is that they don't cinch at the top of the pocket, so things fall out.
