Unused item

Purchased on Amazon in the fall. The trip was canceled due to bears, so it has not been used even once. I intended to use it, so I looked for the box, but it is not included.
Recently, when I tried wearing a knit hat for snow and then the helmet, it was a little tight, so I would like to use this to help fund a replacement. I would appreciate your understanding that only the item itself is included.
