I bought a black turtle neck shirt from the thrift store for 3 dollars and cut out the neck part, it works really well. In fact, I have an accurate neck seal with the ribbing and it velcro's, but it's not made very well and I often get that same skin gap showing at the base of my neck if I don't tuck it in exactly right, so I actually prefer the turtle neck version better. No it's not screen accurate, but once I get my helmet on, you can't really see the neck seal anyways. I like having two different neck seals to swap between.
