After doing my first 3 day DE event few months ago and coming home ridiculously sore, decided to buy support gear for neck and lower back. Ordered this from OGRacing without trying on beforehand but turns out it's too big. Too much slack around my neck where it moves around a bit. Used once and never used again. Not so much for safety but acts as more of a neck support for when looking through the turns with that big helmet.
