LIVACASADrawstring Backpack Gym drawstring Bag Sports for Men Women All Black 2

Is it Machine Washable?

I want to know if it folds up small? I want to keep it inside another bag when not being used...does it compact well?

How much does this bag weigh?

What is the size of the inside pocket? I have a large cell phone and want to make sure it will fit. Thank you.
