Alpinestars Terror Backpack 6100812-162

As some others have noted, the backpack is a bit on the small side. Other than that, though, it's a very nice backpack. Took some adjusting to get it to fit just right, there are numerous straps that need to be adjusted, but once it's in the right spot, it stays put. The padding on it is excellent, very comfortable and has pads in places you wouldn't expect (on both the shoulder straps AND on the part that actually touches your back). The padding helps to keep my laptop from stabbing me in the back, and it gives the backpack a bit of a curve. With a normal backpack, you end up with the "flat" feeling if you have books or a laptop, and it feels like the backpack is barely touching your back. This one is far more comfortable in that regard.

Was *barely* able to fit a 14" HP Envy Ultrabook with a neoprene slip cover. Not sure if it would fit a 15" laptop as claimed. With the (very thin) laptop in the backpack, I can fit one AVERAGE size textbook and a notebook or two. So if you have lots of books (or even 1 big book) to haul around, I'd go with one of the bigger backpacks. For reference, this one is advertised as 17 Liter capacity.

Good construction, zippers open and close properly, helmet holder is effective if a bit unwieldy (I think that would be the case with any backpack with helmet holder, it's hard not to hit people and/or objects).
