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.
Features • 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 • Guaranteed for life • Hydrofil® sweatband to wick moisture away • Keep valuables safe in the secret pocket
