I received this at the Tech World of the Osaka-Kansai Expo. I'm not going to use it, so I'm putting it up for sale. The chin strap is adjustable and can be removed. It comes with a storage pouch with a banana pattern on both sides. Brand new, unused. I just received it, but please understand that it has been in someone's hands once. Thank you. I will use recycled, used packaging materials and ship with simple packaging.
