A while back I was reading an article about helmets and there was a picture showing the inside of a helmet that had a mesh liner that was removable as opposed to just individual pads. Seems like it would be a good feature.

Interested to know if anyone is using a helmet like that and if so, what is it, and how is it working for you.

I'm using a Japanese brand helmet called "OGK Kabuto" which comes with this mesh liner, but I don't really use the liner so can't comment on whether it's useful.
