Hi, I am new here but not new to hiking. I am a day hiker looking for a new pack. I have narrowed my choices down to 3 and I am hoping that someone here might have some experience with some of these and would be able to share your insights. I am currently looking at the Osprey Tempest 20, the Thule Capstone 32L and the Camelback Sequoia 22. They are all close in size, I am mostly interested in comfort. My current packs are frame less and hang heavily when loaded. The load lifting shoulder straps are a must. I intend to do a lot more hiking this year and really need to upgrade my equipment. Thanks in advance for any advise.
