I am trying to imagine how the buckles dig into your armpits.......Definately tighten the chest strap. i have the strap high enough that i can clip it myself behind my neck. And it is reaonably tight but not uncomfortable.

When i put the waist band on, it sits on my hips. Kinda where low rise jeans sit. The top of my hip bone almost lines up with the top of the strap..... Have you ever worn a hiking pack? I have the waist band in the same postion as a hiking pack would be.

Am i making any sense?!

BTW- if you did want to sell, i was talking to someone from BB yesterday who's looking at buying one.......
