Hydration Rucksack Input

[johnnybike]

Just bought a Stormlite hydro cargo 3l rucksack. Never had a hydration bag before but I would have thought that the reservoir would hook onto the top of the rucksack interior, below the zip. I don't see any hook in this bag

Or have I got it wrong

Johnnybike, on my hydration sac there isn't any hook, I simply drop the bladder into the compartment.

Just make sure that you have the bladder the right way up. My Dad really didn't get on with his hydration sac until I pointed out his mistake .
