I'm working on something totally custom right now. I hope to be able to show pictures real soon. But the way I was thinking is: Making a neck-guard for those who hates neck-guards. I stopped wearing neck-guards (and danglers) when I started playing semi-pro in 2004.
It was affecting my head mobility and downward vision and I've prefer to take that risk and "playing better". But now, at the point that I am (beer leagues), I'm tired of collar bones bruises but still can't stand wearing a neck-guard. I can't stand having something bulky wrapped around my neck. So I went into a little project and get a fully custom one.
Also, my neck measures something like 21.5" and I couldn't find one that fits me in stores.
