Lightweight and water-resistant Tyvek leisure sheet. - Brand: Tyvek - Size: 100 x 200cm - Material: Tyvek material Thank you for viewing. The above was written by Mercari AI. I purchased this soft-type Tyvek sheet on this site to use as a leisure sheet. However, I have kept it stored in the closet without ever using it. How about using it as a leisure sheet or a ground sheet for a tent? It seems you can also process it to make bags, etc.
