I have been wearing a Tilley hat since before we started cruising. I wore my hat many hundreds of times in lots of difficult circumstances, like our Gallapagos shipwreck. My hat repeatedly was soaked in salt water and worn in harsh UV light.
Recently I was in Victoria and was able to collect on the Tilley warranty. I was all prepared to tell them all about my travels, but they replaced my hat without asking any questions.
My new hat has the wide brim, air vents in the cap, and has a lighter original colour. I think that these changes will make it more suitable for tropical use, as my previous hat tended to get rather hot. My new hat also has less metal, and so will presumably rust less.
I hope to use my new hat enough to collect again on the warranty.
