They hairy brown nut, is originally encased in a large green fibrous 'case'. When this is removed, some of the fibres from the case stick to the nut. Hence the 'hairy' you speak of.
Thanks Hundreddolla, I have often wondered this as when you see them in tropical places they are always large green things and not a bit hairy, I wonder if they would grow in this country (England) as many plants that were once only tropical have now been adapted to thrive in a climate like ours, As for your answer Craft 1948, That also makes sense as the last time I was in a hot country there was many a bald person complaining of blisters on the bonce
There is a Hawaiian riddle (presumably for kids): Three walls to get to the water, what am I?
A coconut. As $100 said, you have the fibrous yellow-green husk around a hard brown shell, inside the hard shell is a third layer, the �meat�, and then a central cavity containing watery coconut milk. The brown hairy coconuts you typically see are just ones that have had the outer husk removed. Any other hairy brown nuts you see are something else completely.
