Brooklyn-based designer and avid cyclist Vanessa Marie addresses the dilemma of being safety conscious while riding, and maintaining a level of street cred with her 'Night Day Backpack'.
The concept behind the backpack was to create a chic look with (hidden) versatility. The flaps have magnets inside of them with 3M Scotchlite material on the underside. During the day the flaps are held in place magnetically and at night - before jumping on your bike - you flip them up to become super visible.
A variation with smaller squares for writing pixel letter messages to drivers behind you could be fun. Vanessa is second year Masters in Industrial Design (MID) candidate at Pratt Institute.
