"Pipo" in English?

[Rosamunda]

Some boys even knit their own.

Most boys knit their own since this is now part of the primary school curriculum. My sixth grader has been working on his for over a week now. Shame it will never fit him though, he knits so tightly it's going to be really small. A couple of years ago it was quite common to see boys knitting on the bus or on the metro. There was a hat exhibition in the WeeGee talo (Tapiola) last year and one of the exhibits was about a teenager who had even set up his own company designing and making pipo hats and selling them over the internet.

The thicker ones with a turn-up rim that can cover your whole head is a ski-hat or woolen hat where I come from.

I seem to remember the Finns have named these after Jacques Cousteau.

From a cold start, though, the word "beanie" would for most people here conjure up the image of the propellihattu....

That may be so in your neck of the woods, however in the regular English speaking world, people still call a beanie a beanie and a propellor hat a propellor hat!

Yes, very true - Merten Salaisuudet (starring that red headgear) was obligatory watching back in the 70's I wonder if Cousteau is still known among the youngsters of today... the term "cousteau-pipo" might only be known among us relics... still, it gives +450 hits on Google pic search.

Now THIS slogan is another relic: pipo pois - Jippo tuli.
