As far as the construction goes, this backpack seems quite sturdy.  It has adjustable chest and hip straps for stability.  it also has front to back straps to compress the volume if the pack is not full.  The sections that are padded are quite sturdy, and there are loads of pockets.  A semi-hard pocket is on the outside for easy accessibility of sunglasses or a small electronic device.

Unfortunately, the chest strap will not go high enough to avoid pinching a female chest, and the straps over the shoulders are way too broad for me.  Also the shoulder straps are too long for my shorter torso and cannot be adjusted to fit, even at the tightest adjustment.

This would probably be a great pack for a gentleman carrying an ipad or laptop, but it just didn't work for my short torso and fuller figured frame.
