Dutch firm Vollebak has just launched a life-jacket known as the world's most durable with a dyneema-outer surface 15 times stronger than steel.
For years, this extreme sportswear brand has created the best and most durable outfits on the planet. With the "Indestructible Puffer" product, the surface of the shirt cannot be waterlogged or cut or torn.

According to Oddity Central, Vollebak's official website advertises: “Each fabric on the outside of the shirt is 15 times stronger than steel. So if you wear a steel-plated shirt of the same weight, the Indestructible Puffer is 15 times more durable. ”.

Dyneema fibers are commonly used to make bulletproof vests, anti-missile armored vehicles, container ship anchors and ropes to fix rigs in icy waters.
Most life jackets are designed to be lightweight, so the outer layer is usually made of polyester and nylon fibers are easy to tear. However, Vollebak's shirt is covered with 100% dyneema so it is very durable. The weight of the "Indestructible Puffer" is about 2.5kg but will not tear after at least 1-2 years of use. The price is 985 USD.
An interesting point about this life jacket is that it will protect the wearer even better when the ambient temperature is lower. It will increase 5-10% durability when temperatures drop below -50 degrees Celsius. Vollebak claims that at the coldest temperature ever recorded, the Indestructible Puffer will become the most durable shirt with the best protection.
Although called "indestructible lifejacket", Vollebak's jacket is not really "inviolable". Like most life jackets, it is very flammable and can be penetrated by bullets.
