I love my Osprey Talon 44. I use a bladder that has anti-microbial material on the bladder and mouthpiece. Osprey has a deal where you send in your old Osprey pack (doesn't matter what year or condition it's in) for repair and they will fix it for free or give you a brand-new one. My old 44 that had some rips in the outer pocket was replaced by my choice of same pack or similar brand-new pack for free. Love these guys..
