Over a period of years going to the Alps we’ve all eventually bought the same lids just becaus they’re comfortable, light and not too bad looking.
We all wear Casco Vipers, lightweight full face lids. Their chin guard is removable in about 5 seconds with no tools.
We go big enough to warrent a full face lid but not big enough for one suitable for doing 80mph on a motorbike!
I think they are about 450 grams as opposed to 900 grams for a normal full facer plus you still have your hearing and they’re cool (temperature wise) too.
They are quite adjustable (as much as a normal lid anyway) but the chin guard is close to your chin so if you’ve got a big chin you might not be able to talk.
