You've been able to harness the power of the sun with a rucksack for a long time now - but this handsome leather shoulder bag with built-in panels brings solar energy to grown-ups.
The smart Logan satchel will let you charge your MP3 player, phone and other gadgets while you're on the move. It comes from a new collection at Noon Solar, a US-based label that combines sustainability and style with simple elegance. All their leather bags are chrome-free, vegetable tanned and dyed, with different designs for men and women. The prices reflect the fact that these products are designed to last as long as you do, and with that in mind are quite reasonable: the Logan comes in at $412 (just over £200).
