No longer a millennial gimmick (see: the ill-fated ‘mbracelet’ and Helmut Lang’s AW99 spacesuits) the day of wearable tech has finally arrived – look no further than the cover of Vogue China, where Liu Wen can be seen modelling the Apple watch in a shoot by David Sims.

According to a study released in October, the average smartphone user checks their mobile 221 times a day. Engaged in a constant battle against the battery (and lost without a charger), our Instagram habits are burning a giant iPhone sized hole in the environment. Thankfully, Tommy Hilfiger have a solution: the Solar Jacket. The exclusive, limited edition piece is available for both men and women, and has a row of solar panels on the back which charge a power source, allowing you to plug in your phone – or a variety of other USB powered devices – on the go. See it come to life in our GIFs.
