Constant comfort is the aim of our Tec-Wool Hat.
Constant comfort is the aim of our Tec-Wool Hat. We 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.
