Collapsible helmet : Bloom helmet from Toyo safety / 1 pc
The Bloom helmet from Toyo Safety looks like any other safety helmet, but folds down for storage and portability
The Bloom is a collapsible safety helmet designed to be a space-saving and portable. It folds down to a streamlined shape for storage, but can be expanded out to a concave shape in under a minute. This is done by pulling a cord attached to the back of the helmet, which expands the panels until they provide a solid shield against falling debris.
The Bloom comes in a range of colors lime, orange, white, and gray and weighs just 1 lb (450 g).
As well as passing official Japanese safety tests, the Bloom also won a G-Mark Good Design Award for 2013.
