's Raptor 10 hydration packs since April 2010 when it rolled up all shiny and new. It's been everywhere from Scotland to Morocco and back again via my local Peak trails and southern Spain too. It has, genuinely been hammered.Two Years On...Two years later it

Raptor 10.The basic principles of the Raptor packs are the same as the multi-sport packs in Osprey's Hydraulics range like the Manta 25 we recently reviewed, but with some added bike-specific touches and a different shape along with smaller capacities

for racers and weight weenies and the reservoir works just as well on these slimmed-down packs. Our pack also feels softer against the back than the Raptor 10 we've been using.Finally, while there's nothing particularly radical about the straps and back

to reduce the risk of kinking. Lots of small refinements, that should make for a better reservoir.Raptor TweakedThe mountain-biking Raptor range gets tweaked too. There's more venting for the back panel to encourage lateral air flow. The pockets on the hip

.Called the Raptor,it comes in 6,10,14 and 18-litre sizes with prices ranging from£70 to £90. It's curved to match a canted forwardriding position, has no frame and unlike the hiking pack, uses thebladder panel as part of the back system.Again there's no barreling
