I am also selling this on other platforms, so please comment before purchasing. This bag came with a Snap-on helmet I purchased, intended as a helmet storage bag. It might be possible to use it like a backpack, but the material is thin as shown in the fourth photo, so I don't think it can hold heavy items. I have stored it in a chest of drawers after purchase, but I have never washed it, so you might want to wash it once you receive it. I will fold it up for shipping. I am an individual seller, so I cannot provide a receipt. You might be able to use a printout of your purchase history as a substitute. To prevent any issues, this item is non-refundable and non-returnable. Please check my profile before purchasing. Thank you.
