You can boil it, but I don't recommend it. The snaps are polyresin so they'll be fine, but it's hell on elastic.
I recommend washing it with your clothes, anything that you don't need to be absorbent. So jeans, sheets, t-shirts, etc but not towels.
ETA: Bamboo also doesn't need as much prepping as hemp or cotton because of the processing it's already been through to turn it into fabric.
