Bringing this old thread to life just to keep the Tilley hats all in one place.

Just in -- TBC1 Tec-wool Ball Cap
It's a typical ball cap but the material is mostly wool and it has ear flaps. I take a walk each morning with the dog and on days like we've had recently I wear a ball cap under a fleece hoodie (If it's raining, the rain coat hood is over that. The ball cap keeps the hoodie up where it belongs rather than covering my eyes. When I saw the Tilley ball cap it was instinctive and automatic. Next thing I knew Tilley had sent me an email confirming the order; they ship very fast.

Needless to say, it's on my head and very comfortable. I haven't tried the ear flaps yet, but I'm sure they work.

PS: Edit to add that I wore the Tilley ball cap on my morning walk, cold and wet from a T-storm last night. It's definitely warmer than the poly-cotton cap I have been wearing. Not as warm as one of my OR Wind Warrior (pg 1 of this thread), but warm for a ball cap. I still haven't used the ear flaps though and those may bring it closer to the OR WW beanie, but that's built for much colder climates than SOCAL.
