Some people might be skeptical about the benefits brought about by space exploration, but the Surviva Jak may go some way towards dispelling those feelings. The heat-reflective jacket has been developed to keep the body warm in all kinds of weathers – particularly aimed at those who might find themselves lost or stranded outdoors, such as hikers. The jacket recently appeared on BBC Dragon’s Den – the Roadtests.

The shiny, flashy nature of the Surviva Jak – due to the fact it is made of aluminium covered PET – raised a few eyebrows among festival goers at this year’s Rockness Festival, where the BBC took the Jak. The fashion conscious were a little wary of the jacket’s cyber-feel, but ultimately warmed to the product’s heat keeping qualities.

Anyone who’s ever found themselves lost or caught short without enough warm layers, is likely to see how beneficial this item might be. If you missed the Roadtests, you can watch it at bbc.co.uk/dragonsden.
