The unlosable luggage (RADEN A28 CHECK)

The best technology is that which solves a genuine problem. Losing luggage is an enduring worry for anyone who flies regularly. The A28 Check from New York startup Raden is a beautifully constructed case that you can track with a smartphone app, so you’ll always know where it is – even when it is where it should be. It weighs itself, so you never suffer the ignominy of repacking at check-in to avoid excess baggage fees. And it’ll charge your phone up to four times. The range recently launched on MR PORTER, while the app will also help with other travel-related matters such as flight-time updates. Case proven.
