Morpher Flat Folding Helmet

Morpher helmet folded

Its foam construction makes it lightweight and strong at the same time ( just 1 pound/454 grams), as a matter of fact it passed all the safety tests, it has CPSC certification which covers the USA and Canada and CE EN1078 certification which covers the rest of the World, except Australia; the 14 small vents on it reportedly aren’t the best for ventilation but their size keeps the helmet solid.

The folding system is quite clever, when folded 4 magnets keep it flat, at an approximate size of 36cm x 22cm x 6cm, suitable to be stored even in a small purse; to open it just pull out the sides until they click into place. The chin strap on this helmet has a magnetic locking system, making adjustments on the go possible and easy.

The Morpher fits most adults and teens, with a circumference between 52 cm and 58 cm, note that it’s not suitable for very large heads or kids.

The flaws of this helmet are minimal; ventilation is not optimal, especially in hot climates, tough for most situations it won’t feel that different from other helmets. Another drawback is the price, at $125 is not cheap at all, so this product might be worth it for those that really value the folding capability and are willing to pay for it.

  • lightweight
  • easy to store


  • price
  • bad ventilation

Overade Plixi Fit

Overade was one of the first companies to bring us folding helmets, they’re initial purpose was to create a product for all the commuters who use bike or scooter sharing services and therefore don’t usually carry a helmet with them, hopefully they will if it fits easily in a bag, thus the Plixi was created.

The design is centered around the folding function; above your head there is a clip which when opened lets a section of the helmet slide backward, thus allowing the hinged sides to collapse inwards compacting the helmet to a size of 21×11×16cm so roughly the size of a lunch box making it comfortable to store in a regular-sized bag.

Luckily they haven’t neglected the construction’s solidity ensuring resistance to wear over long time use. Its folding capability doesn’t compromise safety, complying with US CPSC & the European EN1078E standards providing adequate protection for commuters. It’s not a very light helmet, between 440 to 490g depending on the size, nevertheless, it’s relatively low considering the folding mechanism and the possibility to customize it with different attachments such as a cover or a visor.

The Plixi “FIT” is the evolution of the first helmet created by the company, in this version the fit on the head has been improved by putting lockable dividers on the straps, along with a variety of padding sizes that come with the helmet should give you a comfortable fit; also the ventilation, which was not ideal on the previous version got a little better with the addition of a few vents.

A very smart product, great as a city helmet, but not meant for long rides or hardcore use; the price is not big, and for the quality of the helmet and its special feature its absolutely a good deal, making it affordable also to students and young people, hopefully lowering the number head injuries.
