Familiarity: I've used it once or twice and have initial impressions
This helmet is really lightweight which is really nice when it in my pack on the way up. It is really easy to adjust and fits snug to my head. I can wear it with a beanie on underneath as well, and it still fits snug on my head. I love the helmet so far and am excited to use it this summer.
