The new Tilley Hat is beautifully made of nylon microfiber. It is much lighter (3 oz. total weight) than the original canvas hat and is extremely comfortable to wear, even on the hottest days. The crown is well ventilated and the brim holds its shape well. There is an effective chin strap. It is not suitable for heavy rain wear due to the crown ventilation; use the OR Seattle Sombrero for that. The new hat is guaranteed “forever”, even against loss.
