Got myself one for Xmas for shorter rides/no sweaty back/see how it is reasons (was gonna get a normal but smaller Camelbak)
I had to work out that I needed the bladder and tube “the other way round” to how it came then I could operate it easier (right handed).
Piss taking from mates – as expected.
One disadvantage is you can’t just spit the tube out mid-drink when you suddenly need to pay full attention to riding because it’ll be hanging down and in a wheel or somewhere…
Had some issue with belt loosening whilst in use but I think some of this may be purely my imagination or possibly my fat belly combined with winter clothing?
To be honest the jury is still out….
