Tilley TTW2 Tec-Wool Hat Tilley Hats Sizes:S- Small developing its own unique characterConstant comfort is the aim of Tilley's Tec Wool Hat. They do that by using c_change technology which independently reacts to changing temperatures. This is a great 3 seasons Hat! Our Tec Wool Hat uses c_change by Schoeller Switzerland technology membrane to ensure constant comfort. What is c_change technology? Much like a pinecone, the c_change technology membrane opens when the outside temperature rises, and close again when the temperature drops.
