In looking at getting a new Osprey pack for hiking, I have narrowed my choices down to two. The Sirrus 24 and the Mira 22. I am coming out of using a Mira from 2014, so I am used to the Mira but mine is too small for all that I want to carry. It doesn't have room for layers like jackets. I am disappointed that the hydration reservoir is not included nor is the magnet to hold the tube in place. My original pack included both. I am 5'10 and weigh 150 and I hike in the the Phoenix, Arizona area during the winter months. I usually go 5-8 miles on a day trip. I have watched the videos at looked at the details on each pack and I can't decide. I would love to go to the store for a fitting but alas, it is not open yet. Please advise on which you think would be a better fit for me. Thank you!
