Familiarity: I've used it several times
I have taken this helmet on a number of adventures, including trad climbing and mountaineering. I've used it in both hot and cold weather. I am very pleased with its breathability and low weight. It fits me very well both with and without a beanie on. The adjuster on the back is simple to use and can be used with thin to medium weight gloves on. Overall, this helmet does everything I need it to and is a great option for the price.
