Great multipurpose backpack
The Angstrom is a very well built and extremely light backpack. I don't do much hiking and so I use this mainly for carrying laptop computers. Both my 14" and 16" laptops fit in this this perfectly. The outer front compartment (no zipper) is perfect for those last minute items that I need to cram in without taking the time to unzip and zip. The velcro secured mesh inner pockets are great for small electronic items and saves the time of otherwise digging through your other stuff. The one thing I would change are the outer elastic side pockets. I did not realize that they have a hole at the bottom corner of each one (this is by design). I almost lost some AA batteries while transporting. For those curious to the size of the holes, a 9volt battery fits perfect through them without much resistance. Overall this is a well-built and great looking backpack!

Fantastic Backpack
An extremely comfortable backpack with all the bells and whistles to match. The straps are a tad long though but they can be tucked and hidden away with ease. The padding and breatheability of the backpack is extraordinary and is defintiely worth the buy.

Excellent backpack
Exactly what I was looking for: laptop friendly and outdoor friendly.

The best backpack I have ever owned.
I purchased this backpack about 20 days ago so that it would be delivered before the first day of my freshman year in high school. It has the characteristics that I wanted and I knew it would be a great backpack for school. When I was reading the comments about "a lousy book bag" I was a little worried. Once I got it and put my belongings into it, I was amazed that someone would think that it is a lousy book bag. I have been one week with my Angstrom 30 Backpack and absolutely love it. It is comfortable and has plenty of compartments. Also, I have to say it looks cool too. As soon as I use this one until I can't anymore, I will be ordering the same exact one. Awesome backpack.

Great FAST dayback. Lousy book bag.
This pack has a very focused design. It is designed to be lightweight and FAST for a minimalist hiker/long distance runner. The straps are very thin mesh with barely any padding but they feature excellent adjustment allowing the pack to be worn VERY snug. The back panel is an awesome rigid foam with excellent lumbar support and ventilation. The fabric is very thin ripstop nylon and other lightweight materials to save weight. The overall shape of the pack is very streamlined and tapers to the top opening with compression straps. The combo of lightweight fabric, thin straps and streamlined shape makes this a very poor bag for a school bag or book bag. The same combo makes it fantastic as a fast daypack.
