Brenthaven 2133 ProStyle Lite Backpack for 15-Inch MacBooks /Laptop / Ultrabook - Black

I love a lot about this bag. The layout is great. The quality of construction is top-notch. The weight, style, and format were perfect for me. But, unfortunately, this is one terrible backpack. The key flaw is that the shoulder straps are sewn on several inches below the top of the bag along a *horizontal* seam. Picture a person's shoulders and you'll realize, shoulders are not horizontal.

The end result is that the straps have to twist to accommodate the anatomical shape of the wearer's shoulders, and as a result, they displace nearly all the weight of the pack along just the inside edges of the straps. This intense stress concentration on one's shoulders and neck muscles is quite painful, especially if you have 10 lbs (5 kg) of laptop, iPad, chargers, and books in the bag. I wore the bag around for a week while on a trip and it was so painful that I nearly exchanged it for another bag while still on my trip. If you never walk more than 100 paces before you set the bag down, you'll love it. But if you have to walk more than a minute or two with this bag on, it's going to become a torture device, and some massage therapist is going to love you.

To my friends a Brenthaven (a company I truly like): Please seek out outdoor equipment designers in Seattle who really know backpacks (I'm thinking REI, MSR, OR, etc..) to help your luggage designers learn to make proper backpacks. There's lots of knowledge in the industry about how to design packs that displace load well. You'll have to put as much focus on weight displacement as you do on those wonderful fuzzy pockets that protect our iThings if you want to make truly great backpacks.

I travel a great deal and need to carry a bit more than the minimum. My standard setup is a carry-on roller bag with a backpack hung onto it, piggy-back style. On the plane, the backpack lives under the seat in front of me, and serves as an excursion bag once I am on site. The Brenthaven 2133 ProStyle Lite is just right for me. It balances nicely on the roller bag and holds my Dell Latitude E6400 easily in a separate compartment. There's an ample center space for files and reading material, and a front section that I use for my Cocoon CPG10BK GRID-IT Organizer, 12 x 8 Inch, Black and all miscellaneous cables, adapters, headphones, etc. The little zip pocket in front is fine for a small amount of quickly stashed flat stuff, like tickets and magazines, so long as they are not quite full-size.

This backpack is slim and does not feel bulky on the back. It fits my mba or 15 mbp just fine. There is a special compartment for a tablet which I use for my ipad. It also fits all the other odds and ends I tend to travel with just fine (mag safe charger, ipad charger, pens, business cards, 3 port power adapter, universal power adapter, mifi) and there is still a lot of room to spare. Everything is organized nicely and items are very easy to get to. I was using a messenger bag for a long time, but switched back to a backpack and am glad I did. This backpack is extremely comfortable and feels sturdy on the back. I could even fit an some spare clothing or a sweatshirt in this no problem. The foldaway water bottle holder is nice touch as well.

If you travel for extended times and you need to carry a lot of gadgets, folders, and so forth, this is a great backpack to do this. I have used it in several trips and I can store in the over head compartments of the smaller airplanes with no issues. It is very well built and the straps are very comfortable to wear.
