I would agree that for hot days and short day hikes the lumbar pack excels. We have been using Kelty Orioles for several years on our prairie hikes. Hers: blue, his: grey. Carries just enough. I do like the MS packs, and I might pick one up soon. I prefer a small backpack when I'm wearing a heavy coat though.

Looks like REI is clearing out their 2013 model year lumbar packs
