Make it breezy on yourself
SONY REON POCKET 5
If you thought the baseball cap with a fan built into its peak was the pinnacle of wearable technology, get ready to have your mind blown. Or, more accurately, your neck. Essentially a tiny air-con unit that clings to your back, the Sony Reon Pocket 5’s thermoelectric cooling plate sits against your skin and heats up or cools down based on what the temperature, humidity and motion sensors inside say; or you can pair it with a separate wearable sensor that reacts to the outside conditions. There are five levels of cooling and four levels of warmth, and you can also control it with an app (available for both iOS and Android)… but you’ll still need the cap to keep the sun out of your eyes. £139 / sony.co.uk
