Question 3

With such a big lid for filling, how are you to get the full 2 liter's in? Is it 2 liter's starting under filling lid?

Accepted Answer

I found no way to successfully fill this bladder with 2 liters of water without a bunch of it spilling out when you screw down the cap. Another reviewer reported capacity at 1.6 liters.
