The thickness is 0.4 mm for this shown model.
It's also possible to make it from thinner 0.25 mm latex - please check out the currently available colour's list in the policy section.
It has a hidden zipper at the back with an underpiece to protect your hair from stucking in between the teeth.
It's possible to mix/change the details on my hoods. For example changing the colours, adding a detail seen on another one or making them without a detail you can see on them on the pictures. Don't hesitate to ask. :-)
Please check out the currently available colour's list in my policy section or just send me a convo about the possibilities.
