The Patagonia Woolly Hat includes a lightweight polyester lining to eliminate the itchy feel of wool and add a bit of warmth for those really cold days in the mountains. Large earflaps keep your lobes from freezing, and Patagonia added tassels to the Woolly Hat because, well, because they're cool and they blow in the wind.
This Patagonia Woolly Hat is very nice, the colors were just right to go with the rest of my outfit, the liner on the inside is very warm and it feels very nice on my head.
