The sternum strap is not adjustable in height only width. There is no stretch cord. It is a great durable backpack and does have lots of straps to adjust for comfort!
Jerry T Thanks for the reply.
I'm buying a gift for a female. I saw a video of the standard Kelty Shrike and what I really liked was the fact that the sternum strap slid up and down on the shoulder straps and had a little bit of stretch. Is this true of the standard Kelty Shrike, SKU: KLTPS, you have for sale, not the women's version?
