best protection rating... (currently)

I've used it several times

fwiw this helmet currently has the best score from the Virginia Tech helmet testing lab of all the MTB helmets they've tested (and they've tested a lot). their tests ... "Our bicycle helmet impact tests evaluate a helmet's ability to reduce linear acceleration and rotational velocity of the head resulting from a range of impacts a cyclist might experience." This is a highly respected testing lab. They also test helmets for other sports like Hockey, Football, etc.

Sizing beware

@competitivecyclist your sizing guide for this helmet is wrong. For the large you have the Tactic 3 helmet sizing which is 63cm. This is the Tactic 4 and the large only goes to 62cm as is posted on the specialized site.
