Waterproof, Large, Hydration packs for cycling?
Can anyone tell me a large Hydration pack which is waterproof and suitable for cycling. I am talking 25L plus capacity with 3L water reservoir.
I know about the Ergon BC3 (but i need other options). http://www.dotbike.com/p/5523?utm_source=google&utm_medium=base&utm_campaign=FGL
