Something else to consider is duration of hike, not only in miles but days. I have 1 pack and it works well for everything for me, but I’m not a through hiker. I can take my 8 year old on a 3 mile overnight and carry extra weight/gear and it’s no problem. I can go on a solo multiple day trip with the same pack and it’s great. It weighs 2 lbs 10 ounces. Under $200. I think this pack gets hate because of its brand, and the attachments, which can be removed. Rei flash 55. Review plz?
