Alpinestars BNS Tech-2 Neck Brace - Black / Yellow Fluo

It's not too obstructive for me when riding and would seem to add some much needed protection for my neck, hope I never need to find out for real! However, I found the pads that came with it to be rather insufficient to get a good fit and could really only secure it as specified in the instructions using the supplied straps which cross your chest and fit under your arms. But once in place, it's easy to clip and unclip. The style of helmet you use affects the performance of the brace, mine is just about OK based on the tolerances listed in the instructions but some helmets may not be compatible with it, so best check this out first before buying.
