Ordered the Regular and it fits perfect (although I am average size and I thought I would have to adjust it to the lower end of it's adjustment range...but it needed no adjustment). Carries load very close to your spine. The hip belt and shoulder straps are very comfy. On the down side, I wish it had bottom access, a rain or snow cover and hip belt pockets. Colors/patterns take a little getting used to.
