Vollebak Indestructible Puffer Jacket
Vollebak’s Indestructible Puffer is touted as the “world’s strongest jacket,” and rightfully so. It’s made from 100% Dyneema, which is apparently 15x stronger than steel and 40% stronger than high-strength aramid fibres, which means it can withstand shearing, tearing, and blunt-force traumas with ease. In early tests, the mooring lines were so strong they even broke the machines meant to be testing them, and the body armor stopped bullets from a Kalashnikov.

This jacket weighs 2.5 kilograms, but it’s designed to last a lifetime, or more. That’s not all, it gets stronger as the temperature drops, or to be more specific, a 5-10% strength increase when the temperature drops past -50° C. There’s just one caveat: it’s priced at $985.

We’ve taken the puffer jacket – traditionally one of the weakest and most delicate pieces of clothing you can buy – and rebuilt it from the strongest fiber ever made. Every fiber on the outside of the jacket is up to 15x stronger than steel, so even if you were wearing a steel-plated jacket that was the same weight, the Indestructible Puffer would be 15x stronger. The material we’ve used is so tough it was originally used in body armor, anti-ballistic vehicle armor, mooring systems for giant container ships, and ropes used to tie down oil rigs in violent, icy seas,” said the company.
