My 2 cents on one of their packs ...... I have owned a few good packs in the past(the latest being a Kifaru Siwash) but I will say is that you can use the crew cab (w/the NICE frame)as a comfortable and compressed daypack or load it to the max (150 lbs ++)of what your legs and back can handle and you will not have any sore spots because of the pack but rather from your own deconditioned body; and the Mystery Ranch customer service is top notch.
