The Tipperary Sportage helmet is a ASTM-SEI certified (ASTM Standard F1163-15) helmet. It features an aggressive cut away profile in carbon fibre print with functioning top and rear vents for high temperature relief. The helmet also features contoured back drop shell and comfort foam interior that cradles the head for increased protection.
When I crashed mountain biking last year (huge fall resulted in crushed hip, bleah), my helmet was dented but my noggin was as good as it's ever been haha. That reminded me that my Tipperary was overdue to be replaced, so the 'safety sale' was handy. I just got the updated least expensive version; if you check CSI safety studies, some of the most costly helmets aren't any safer. The only time I smashed one I was galloping a track TB, and my Caliente helmet really just had some deep scuffs! Yay helmets :).
