After a chat with Osprey at a trade show, they have agreed to throw some bags my way.  Went out for my first ride with one of my new bags (the Raptor 10).  After using such a great bag I gave away my old Camelbak.  This is possibly the most comfortable bag I have ever used.  I really like how easy it is to fill the bladder and to put it back into the bag - this is to do with the hydraform back panel and this also makes the bag more comfortable.  The magnetic bite valve is fantastic.  There was plenty of room for all my stuff and the separate compartments make for easy access.  I would recommend this bag to everyone.  Looking forward to using their other bags.  A big thanks to Osprey for their generosity and support.
