Let\'s see your Signifer and Aquilifer animal pelts

[M. Demetrius]

One thing to consider is the leverage that the skin would put against the neck piece of a conventional helmet. That would be very tiring to the wearer. My guess is that the neck piece would be as small as possible on a helmet like that, or not on there at all. And I suspect the arms tied together in front were to transfer some of the upper weight off the neck muscles, and onto the shoulders.

A tanned bear skin can easily weigh 6 kilos or more, depending on how much it has been thinned in the processing, and how big the bear was in the first place, whether taken in summer or winter, etc. And that assumes they tanned them in more or less the same way we did.
