What improvements were made from this bag to the Coyote 80? Are the advances worth the extra money? I am buying this for my 16 year old son who will be hiking at Philmont next summer.
Kelty renamed all of its new 2011 packs in liters instead of cubic inchs. So the Coyote 80 is the updated 2011 version of the 2010 Coyote 4750. The differences include. The stays are not parallel which focuses weight on hips for easier carrying, the hip padding is different and it has an HDPE sheeting. If these things are important to him then yes its worth the money, but the 4750 is still a great pack regardless of the updates. Stay safe and have fun out there! Neal
