Most of us won’t ever need a light while climbing Mount Everest, but if you did you would want to have the S.T. Dupont Defi Extreme Lighter ($140) on hand. This lighter was made to perform in the most extreme weather conditions. Made from high precision metal, the Defi Extreme can withstand extreme winds, temperatures down to 14 degrees, and work at heights of more than 3500m. The beautiful ergonomics and feel also makes it a great daily lighter for any situations.
