Does this pack have a sternum strap? (adjustable across the chest)
How comfortable are the shoulder straps? I am looking at this for a BOB but in my experience shoulder straps are a make or break. Many packs and rucks are awesome until you tote them for 4-5 hours when the straps just start digging in.
Why is this item $20 more on Amazon than it is from the 3vgear.com website?
