THE packs cost 99 bucks at AAFES.
Busta, your suggestion may work for some. For others, good luck getting your hands on a RAID that you didn't have to wait 4 months for!
I like my BL Hydration Patrol Pack. Perfect size, and nice features. Downsides? A bit expensive at 75 retail and no straps for use as a stand-alone pack.
Then again, If I need a stand-alone hydration system, it means I'm hiking or M Biking and my civvie CB will do. Whenever I need storage and hydro at once, I'm wearing my full kit.
