A university website linked to in the article suggests that a helmet that costs half as much as the one advertised in the article performs slightly better: https://www.helmet.beam.vt.edu/bicycle-helmet-ratings.html https://www.helmet.beam.vt.edu/bicycle-helmet-ratings.html Look for "Lazer Cyclone MIPS". Edit: Unfortunately it appears that this particular helmet has been discontinued: https://www.bikeforums.net/general-cycling-discussion/1174734-lazer-cyclone-mips.html https://www.bikeforums.net/general-cycling-discussion/117473... But there are others that perform about as well that are similarly priced.
