I am using camelback rouge for hydration. LOVE it! a bit limited for storage. but that is what bike bags are for.
On the other hand my road pack is an Osprey talon 22. Love Osprey as a product, hate their business ethics. They are right up there with shimano at abusing the people that keep them in business. My opinions might not align with others on the matter.
regardless I'll push people towards Camelback
