Initial Thoughts:

I am sometimes hesitant to carry more safety gear that I may or may not need. Luckily, I hardly notice the addition of my Petzl Elios helmet. At just over half a pound (size small), it adds very little to my pack weight. With the plethora of adjustment options, I was able to achieve a comfortable fit before my first climb with it. I like how easy the rear headband adjustment dial is to use. I can easily change the fit for use with or without a hat underneath.

In The Field:

I recently used the Petzl Elios helmet on a successful climb of Mount Hood (Oregon's highest peak at 11,239'). The last stretch of our climb went up a chute prone to falling ice (and rock later in spring). I really appreciated how light the Elios is. It easily fit in my 40+ liter pack until I needed it. Once I had it on over my beanie, I forgot it was even there. The fit was tight enough to keep it firmly on my head, but not so tight that it cut off circulation or caused discomfort. I literally didn't even realize I still had it on until later in our climb on the way down when the sun started beating down on us. I started to get warm and wanted to remove my beanie, at which point I realized my helmet was on.

See Mount Hood adventure where the Petzl Elios climbing helmet was used.

Final Thoughts:

I am now a believer in the value of a good climbing helmet. After seeing chunks of ice whiz by my head, I appreciate the protection a helmet offers. I highly recommend the Petzl Elios helmet. It's lightweight cheap insurance. Available from amazon.com.
