How exactly does it work? I should put it inside the backpack? Can it be used in any kind of backpack?

Hi, dear customer. Thank you for your question. This is Amanda here to serve you. About our hydration bladder, we have attached detailed instruction on our package for you to quick start on using hydration bladder. Here is the instruction for you. 1.Open the cover by counter-clockwise, and close it by clockwise. 2.Gently bite and pull the tip of the valve with front teeth and push back to stop water flow . 3.For the best results,please do not bit hard or chew on the valve. 4.Please cover the valve when not in use. About your other question,our L 14.2'' x W 6.8'' Hydration bladder is compatible with most hydration packs. When they hydration bladder is empty, it can be folded .So it won’t occupy much room in your backpack. The tube (0.4” diameter, 40” long) provides a wholesome flow for easy drinking, keeping you hydrated when biking, cycling, hiking, or running! You will love this hydration bladder when you get it. Please feel free to write to us if you have any more questions, we are here to serve you all the year around. Regards.

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
