OMG I think I am the Camelbak Queen!
I have:
1. the Flashflow waistpack for running and XC ski skating (the shoulder straps are irritating on the backpack style with the arm motion)
2. the Hawg for long road and mountain bikes with a 100oz bladder
3. A minimalist one with a 70 oz bladder and a neoprene covered tube for downhill skiing
4. a big honking REI backpack with room for a 100 oz bladder for long hikes where I need to carry a bunch of stuff
I'm sold on them.
