I like that this hat is stretchy. If I feel like covering more of my ears, I can pull it down, etc. It's comfortable and easy to adjust.

But this is NOT a hat for truly cold weather. I would not recommend this for use in any temperatures below 32 where the sun wasn't shining or where there is significant wind.

Wind rips right through this hat. The same stretchy nature that is a positive is the hat's downfall. The wind penetrates easily through this hat. It may keep you alive, but you will not be comfortable.

Another hat I have that I love is a wool hat with a liner inside that blocks the wind. It's a tighter, less adjustable hat, but it is soooo much warmer. I don't see it for sale anymore or I would list it.

So in summary, this Carhartt hat is great for cool-ish temps, but not suited for cold weather.
