Hi - It sounds like the pack torso size is too small for you. Please call Osprey customer service @ 866-284-7830. They have experts on hand that can help you with the fit process.You can do this yourself by using the torso length measurement. To find your torso length, measure your back along the spine from the the top point of your hipbones to the knobby bone at the base of your neck. This will give you a measurement in inches that will determine the correct pack size. I would use the aforementioned procedure & find your correct size.
