Snap, Tony. Except I seem to have avoided most of the name calling, other than my dear wife objecting to me using the 'chin-straps' to keep it on (rather important above F3: although the hat does float, leading to nifty single-handed 'hat overboard' recovery manoeuvres*) commenting, repeatedly, that the straps make me 'look like an elephant with toothache': unsure how she reaches that comparison.
Having had my hole-y Tilley replaced, they didn't confiscate the old one, so I literally have two for the price of one, and the hat in the rather fetching (I think, anyway) portrait of Cavatina in Water Craft is still the old one.
There is allegedly an elephant keeper at a zoo in the US/Canada whose Tilley hat has been through the digestive tract of a playful elephant, who ate it not once but twice.
Talking to the delightful Tilley UK ladies on the phone, I asked if they have to replace hats often under this generous lifetime guarantee. 'Oh, quite often". How often is that? 'About ten a week'. That's about 500 a year in the UK. I suppose it accounts (partly) for the initial high price. Still, definitely worth it if you use it enough!

*Tricky word to spell. Quite pleased that I got it right without resorting to looking it up - or is someone going to tell me I got it wrong?
