I am 50 years old and have not had a pack hunt for 20 years. Getting in shape and want to get a pack to give it another go. Looking for a pack for at least a week long trip in the rockies. I am looking for the most comfortable pack as possible. For what it is worth I am 6 foot 210 lbs with a 46"chest and a 34" waist if that matters. Was looking at the Eberlestock, Mystery pack and Kifaro. All input would be appreciated.
