Please - no baseball caps..!!!
Absobloodylutely. Pictures of my in my Morgan cap show that it is not suitable at all - so this barely worn cap will probably be going in the For Sale section soon. But that presents a problem of what to wear in the summer that is light and has some sort of peak. Currently it's a pith hemet (I kid you not...)

In the winter it's a fur-lined leather helmet. Bought a new one in Jokkmokk, northern Sweden, last year. Reindeer skin, arctic fox fur and sheepskin lined. Tasty!
