How do you recommend this being washed? I just received this today

Hot water and 2 tablespoons of baking soda.

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?

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.

Any way I can order a longer tube? I would like to use this while motorcycle riding

I have not found a specific one but you could us aquarium tubing of the same diameter
