helmet padding

I saw a helmet here that used football padding on the inside... where can I buy just the padding itself?

I got mine at a sporting goods store.

How does that work for ya BobaN00b?
I have still to do some type of liner in mine.
Any other suggestions?

The stuff I bought goes inside of a snowboarding helmet. I have not been able to find the exact same padding I use, but this is the closest I could find:

I glued mine in with hot glue and it works well.

get a couple of big spounges and then cut them into desired pieces. Or the hard hat liner always works
