When you're having to bring your mode of transportation with you into the office, size reduction matters — and Uncrate.com reminds us that while they've covered folding bikes before, they're only part of the shrinkage equation. The Overade Folding Helmet  addresses the rest. This protective bicycle helmet was designed to save room once the ride is over by folding into a palm-friendly size that's just one third the volume of the helmet when worn. And for a few extra bucks you can also get a matching protective cover and visor.
