Unusual but true: Chocolate wall in Netherlands

World's strongest puffer jacket

Dutch brand Vollebak has created the world's strongest puffer jacket, which is 15 times stronger than steel.

The exterior of the indestructible puffer is made from 100 percent Dyneema, the strongest fiber ever made. Dyneema was originally used in body armor and anti-ballistic vehicles, armor mooring systems for giant container ships, and in the ropes used to tie down oil rigs in chaotic seas.

The puffer is made to withstand temperatures up to -40°C, as the colder it gets, the stronger Dyneema becomes.

"Most puffer jackets are built to be as light as possible, so the outsides are typically made from super-lightweight polyester and nylon," explained Vollebak's co-founder Steve Tidball.

"We wanted to create a jacket that could withstand the toughest challenges in the toughest places on Earth. It will withstand any abuse you put it through during your lifetime and be in good enough condition to pass down to your grandkids when you're done with it."
