Bontrager Specter WaveCel
Bontrager’s Specter WaveCel has 14 vents in its EPS core, with a beautifully finished outer shell completely covering the underside and all other vulnerable areas, plus a reflective patch.
Within this is the WaveCel liner, which is a collapsible cellular structure, said to be many times more protective than EPS alone in certain scenarios. My large test model weighed 391g.
It sits very low on the brow and temples, meaning the arms of some glasses may be a snug fit, and its more ovalised front appears in your peripheral vision.
The Boa-based retention system has multiple heights, and the occipital cradle grips the skull perfectly for excellent security, while the straps fasten with a Fidlock magnetic sliding buckle.
The WaveCel layer is separated from the EPS and polycarbonate outer shell, so air can move freely between the two and your head doesn’t contact the insulating EPS.
As WaveCel’s cells are perpendicular to your head, they generate constant airflow, which is pleasant, especially in cooler weather because it prevents your head from feeling too cold. However, this helmet does creak occasionally when you move around.
The Specter WaveCel is weighty, but doesn’t feel it when worn. Its compact shape should protect more than ‘standard’ EPS helmets, and it features a reflective patch.
