Nokia went to New Zealand during Burton High Fives contest to find out what snowboarders think about the Nokia x Burton Insulator Case.
From the main product page:
With 3M™ Thinsulate™ insulation, a Nokia X Burton Insulator Case will protect your phone from the cold and snow, as well as keep your battery alive for longer.
Wrap your phone in cosy, stylish layers inspired by Burton’s 2012/13 collection and you can extend its battery life by up to 50%* in cold or sub-zero temperatures.
Close at hand
Each case is tailored for protection with a carefully crafted zip finish and leash that lets you keep your phone, cards, cash and keys attached when out on the slopes.
50%, eh? That's quite a claim, but credit where credit's due for bringing this environmental effect to more people's attention. Batteries are fragile beasts at times, you know, best keep them charged and keep them warm!
