Reviewed by Kram - 9th Mar, 2018 Tilley TTW2 Tec-Wool Hat I have not owed this hat for long, so there is not a lot that I can say. I am impressed that it comes with a life time guarantee. It does not matter if you sit on this hat, it just goes back to shape when you put it on. It fits well and looks great when you wear it. i have just treat my self to a silver broach, of a stagg jumping, which looks great pinned to the side of my hat.
