>>389674I just had a week of urban exploration and short /out/door hiking in the Southwestern US using a Kelty Redwing 50.
Fan-fucking-tastic bag. I can't say enough good things about it...though I will say that the 50 is a little big for day-to-day stuff unless you are packing a lot!
Disclaimer: This is my wife's bag she uses for camping. I use Military Surplus (ALICE Pack (Med) with frame - yes, Dave Canterbury convinced me on the dual use stuff) and love it but holy shit this bag was nice.
