The Tilley T3 Hat `I`m the proud owner of a Tilley Endurable Hat. I bought my now beat and battered (but unbowed) Model T3 more than a dozen years ago. It truly is a fantastic bonnet Members of the Tilley League are fiercely protective. A mystique has evolved around The Hat (and I feel I) am almost invincible with my Tilley upon my head.` Jack Blosser, writing in the Flint Journal, Flint, Michigan GUARANTEED FOR LIFE INSURED AGAINST LOSS EXCELLENT SUN PROTECTION REPELS RAIN TIES ON IN THE WIND MACHINE WASHABLE (WON`T SHRINK) Perhaps most wonderful of all (Please scroll to the very depths of this page to learn something that continues to amaze and delight Tilley Hat wearers!)

A lifetime investment in sun protection and smart appearance. Measurements: Front and Back Brim 2 3/4", Sides 2 3/8"
