I currently use the Leatt Adventure II brace. The product is amazing! Prior to using the Adventure II, I experienced bouts of whiplash and moderate to severe neck pain, from either rough landings or unfortunate mash-ups. Since using the Adventure II, not only have I not experienced whiplash or neck pain, I have also been able to ride without restriction. My old neck brace restricted my ability to look side to side, severely hampering (or should I say prohibiting) my ability to look over my shoulder. The Leatt brace allows free side to side motion, thus I am able to look over my shoulder; in fact, the first time I rode with the brace, I forgot that I was even wearing it. Two thumbs way up for Leatt! Whether racing or pleasure riding, I now refuse to ride without my Leatt brace.
