The price tag hurts, but I just picked up a Stone Glacier EVO 3300. This seemed like the perfect size to go from day to couple day pack, yet not sacrifice the ability to pack out meat. I did purchase the 500 lid for it to add that little extra spot to store quick access stuff like binos and such. For the couple times I have used it for a day hike all I had to do was sinch it down and it doesn't move despite having very little in it.
I like the colour and can use it for work and play.
Load shelf held a 40lb sand bag and a full pack without issue on my second test outing. The frame and harness is decent, though for a day only pack is probably over kill. Though the ability to switch bags, or even drop the bag for just the hauler is what sold me on it.
I'm going to do a review on here after I get some more time on it.
I am a big dude so I have the opposite issues, but the large belt, and the endless adjustability helped greatly in getting this pack to fit right on me. They offer smaller belt sizes as well and a good video on how to adjust it properly.
