Have Dakine Nomad, had Evoc CC 10L. Session and CC 6L are a bit different. Maybe try a bum bag / fanny pack.
They are both very good, sturdy packs, but prefer the Dakine:
* Nomad came with hydrapak bladder, replaced the mouthpiece with camelbak (much better).
* The routing for hydration hose is a bit fiddly on evoc, the internal mash pocket gets in the way.
* Nomad has a magnet to fix the hydration hose on shoulder strap.
* Nomad has a separate compartment for hydration bladder.
* Nomad is better organized, more pockets, armour straps.
* Dakine has smoother zippers.
* You have to unclip the front flap on Nomad to access the front pocket.
* Evoc fits me a little better, has a bit better ventilation and is a bit more stable (longer, slimmer, smaller).
