Discussion right up my alley. I have been running with a Kuiu for 6 years and have a smaller frame at 5'4" and 145 lbs. Kuiu was fine for most applications, including 3 day backcountry pack in and Alaska Fall hunt. However, I have noticed that shoulder straps don't fit well and even at the shortest adjustment on the Kuiu I still have a 1" gap and with substantial weight (1/4 elk hind and back straps with 3 days of gear), the pack slips down to my tailbone no matter how tight the suspension belt because of the inability to get the shoulder straps closer to the top of my shoulder. I have been looking at Exo and SG x curve. I am not a woman but looking at female specific packs hoping for a better fit.
I would be interested to hear from guys or gals in the same boat - while not all hunters are 5'6" or more and 165 lbs or more, I understand that these companies cater to the most common demographic.
