So I'm going to be needing to line my helmet soon, and I don't know where to begin to look for foam liner. I tried a local Modells looking for like a replacement liner for a football or baseball helmet (even hockey would've worked) but no go. I search ebay for "foam" and get about a million hits, and foam liner gives me about half a million. =) Is there a specific brand or keyword I should look for? Should I be looking at a specific store? please let me know!
