After the 2011 earthquake, many people here realized how important it is to prepare an emergency kit, just in case. Probably they bought some emergency food or a flashlight, but I guess they couldn't save extra time or space preparing a helmet. Neither could I.
For those who haven't bought a helmet yet, the BLOOM folding helmet for emergency purposes, sold by Toyo Safety, might be a worthwhile product.
You can keep BLOOM as it's folded, and you can pull a string connected to the helmet and shape it like a helmet in a state of emergency. Anyone, including kids, can use it easily.
BLOOM won the Good Design Award 2013. Price: About 4,000 yen Color: White, Orange, Gray, Lime Weight: 430g
