Happy with my 661 Core Saver without breaking the bank. Picked it up for $95. Fits well and doesn't ride up. The lower elasticized waist/kidney strap has lots of room for adjust and you can actually wrap a tube around your waist just above the strap and you don't even know it's there. Micro-pump in the pocket and you're golden. Sounds weird, but it works.
you can snap off the upper two spine guards as well if you're running a neck protector.
Any LBS carry these?
