Positive and Negative
The chest strap is horrible, I took it off immediately, I'll get some use out of them as compression straps on a stuff sack or something though, they have nice metal clips. I like the side zip computer sleeve, it offers easy access and lots of padding. This is a great laptop bag for college or high school.

Stylish, good quality, good for biz travelers and commuters
This backpack is slim so there's not a ton of extra space. It has pen holders and stuff on the inside which I didn't expect. The outer pockets are small. I wish there was a secret stash pocket. But overall it's stylish, well-made, and uses recycled materials. Keen is a great brand.

lightweight and very simple design
i just received my new keen burnside daypack so it's hard for me to say how it will last...which is really important to me. i switched to keen from lowepro because i found the lowepro laptop pack too heavy when traveling internationally. the burnside is much lighter but i am seeing a few things that really bother me about it. 1) is the very aggravating and flimsy aluminum chest strap hook 2)no external side zip compartment for cell/water/or ipod. inside is basically just one big open area...so my small handbag does fit in there. i think this will be a good bag to just take with you in the city if you want your laptop and room for a small bag or camera...but there is not enough shoulder support to make walking a long distance comfortable. maybe it will grow on my and i'll get used to the simplicity of it. i'm giving it an above avg. rating because i really like the side laptop pocket and because of the lightness.

good design, poor build quality
nice design, comfortable even with 15.4" 3kg laptop inside, cool looks - but poor build quality (stitching). came apart on front patch of right shoulder strap where the Keen logo is, and along the main zip. Otherwise, a decent bag.
