Outdoor Research Frostline Hat Reviews:


Warm and functional

Very nice hat. Very warm and good build quality. Haven't had mine for very long, but I expect it will prove to be quite durable. I especially like the stowaway face mask. I find it fits rather small. I have a 7 3/4 hat size and the XL is small on me.

Comfortable and very warm.

The face mask is perfect for extra windy days.
