Bern Morrison Bern's premium cross-over helmet, the Morrison is equally at home in the urban jungle and on the trails. A hard visor, ample venting, and premium Boa adjustment system (new for 2016) make this lid stand out both functionally and stylistically. The 2016 Morrison features our new Zipmold+ and Boa retention system. Zipmold+ is our proprietary liquid foam construction that is thinner, lighter, and stronger than traditional EPS construction. This allows for certified and safe helmets with an ultra-low profile and fit. Designed with 16 vents there is more than twice as much airflow than Bern's other leading bike models to keep one's head cooler on those warmer summer days. The performance liner with adjustable dial allows for a customized fit with moisture control and is replaceable should one need to freshen up a bit.
