Worn ONCE in pet-free home. Men's size Medium. Model pictured is 5ft 11 / 180cm with a 38 inch / 97cm chest, and wears size Medium. 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 fibre ever made. Every fibre 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 armour, anti-ballistic vehicle armour, mooring systems for giant container ships, and ropes used to tie down oil rigs in violent, icy seas. In early tests the mooring lines were so strong they broke the machines that were meant to be testing them, and the body armour stopped bullets from a Kalashnikov. So when we went to build the toughest puffer jacket ever created, there was only ever one material we could make it out of. Built to see you down to -30°C the jacket comes in one colour, black. And one mode, tough.
