Phrygian cap under helmet?

[Giannis K. Hoplite]

I was wondering for a long time what the wide straps some times seen under the helmet were. They're visible in sculptures mostly,but also in coins. Those straps have been discussed in the past and some said they may had been to tie the helmet but they can't be. Some talked about special padding caps under the helmet,but what I think they were,is just the phrygian cap with its ear coverings tied over the head. look at some pictures and tell what you think.

I also found that a cap that has ear coverings is very comfortable. The helmet is very tight around the ears and this is where the weight goes when you bent your neck right or left. However,I couldn't hear as well with it. And also,I haven't seen hoplites wearing phrygian caps in vases. But this is off the top of my head,I can be mistaken.
