I chose this pack for its streamline design, size and weight. It fit very well, too. The fabric is very taut over the rigid frame, so much so that some of the material didn't seem to stretch properly causing the frame to squeak when I flexed forward. I received great customer service from Campsaver, and returned the pack. If it was in fact a manufacturing error, I'd consider getting another one, since I liked the features.
