I needed a helmet I could use in the winter for the snow and summer for the whitewater. I love the Bern helmets. With snap in features they work well for all seasons. I used this helmet for a 16 day whitewater trip on the Grand Canyon section of the Colorado river. It fit snug, but shaped to my head soon enough. and the visor was actually functional, not just fashion. -Here it is in use on Hermit Rapid. Kept my head safe when gravity pulled me out the back.
