Honestly, Tvyek is pretty miraculous. It’s permeable to water vapor but not to water, it’s nearly impossible to tear, but can be easily cut. It’s cheap and made entirely without binding chemicals. In addition to being used for wristbands, it’s used to wrap construction sites to keep out water during construction, for tear-resistant envelopes at Fed-Ex, coveralls for mechanics, and my wallet, actually.
Fun tip, though it looks like paper, Tyvek is plastic, and cannot be recycled with paper.
Make a bomb shelter that’s made entirely out of Nokia phones wrapped in Tyvek wrist bands.
