I have an ALICE pack in the trunk of my car. I have a large hiking bag and a CFP-90 as my BOB's.
I like the ALICE pack. Have a couple that I use for special situations: whitewater rafting, short hunting/fishing trips, etc. I would still have my ALICE BOB but it was old and worn and I needed a replacement and something with a slightly larger capacity...the MARPAT come along at the right time and at the right price.
