On a totally separate note, any stores in the US stores carrying the hats?
Context has the crusher and bucket. Jonathan & Olivia in Canada has the crew cap. I bought a wool crew cap from The Bureau when I bought a landsdown jacket. Normally, I don't like the one size fits most cap because of the gap in back with the adjustable plastic thing, but the design solution on the crew cap is pretty good.
There is a fabric strap that adjusts the size of the cap, a metal buckle that holds it in place, and the extra strap has a metal tip end that tucks the extra fabric into a slit.
