Full description

Now this bit of kit is brilliant, and in more ways than one. Make no mistake, one day it could save your life. It’s a super-light head torch, so small it will fit in your pocket, but put it on and this light will shine a path 20 metres in front of you and, in extremis, will keep on going for almost two days. It’ll work at 30? below and in up to one metre of water. James Bond, Bear Ghrylls, eat your heart out!
