Yeah, I got one earlier in the year. So far it’s been great.
Main reason for getting one was a bad collarbone break 18 months ago has left me with a nasty lump right where the straps sit of my previous camelbak, so the weight of the bladder caused me problems after 1:30-2 hour rides.
With the bladder round the waist I haven’t had any pain since. Also, it is easier to keep the LR snug against my back and it doesn’t want to ride up towards my shoulders when pointing down the trail.
Not as much storage as previous pack, but I can live with that for the increased comfort.
Wouldn’t go back to a standard camelbak now.
