Accepting that head neck restraint devices are a good idea for HPDE & track driving. I have not used one before and a quick search reveals the typical 1x-5x price range with various styles, whistles & bells.
What advice & comments do folks have regarding model selection, fitment & personal preferences for a first time shopper?
Addendum: FWIW I have Schroth 6 point. 2" webbing. But interested in general comments as well.
