SOURCE Product Reviews (Page 4)
Actually I have three WPX 3L, one Kangaroo 1L and one WLPS Low Profile 3L, that I use for MTB, hiking and Softair.
Source are only hydration system that don't release taste.
I have also an Assault 20L Hydration Cargo Pack that is perfect to one day tours.
Very good materials.
Honestly, I'm lukewarm on the accessories, since the magnet isn't strong enough to hold the hose snug to the curve of my shoulder strap, and the UTA only helps if you fill your bladder from a tap, rather than wild water.
It would get a lot more use if there was a cut to length hose kit, or at least some options for length, so I could have the right setup for whichever pack I'm using.
Just use a grimlock, carabiner, or bungee tie and accept that the rest of the hose will stick out a bit. The stiff hoses generally stay out of the way anyhow.
