Constant 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.

Look forward to:

    - Constant comfort – c_change™ works to maintain an even temperature
    - Keeping warm – discreet tuck away ear warmers can be pulled down in cool weather
    - Staying dry – fabric repels both rain & snow
