Here's what other sites are saying:
At first we thought Sierra Designs had gotten its geography a little mixed up with the Tarzan Peruvian Beanie. But then we realized it was made from Cheetah Fur, an extra-warm, fuzzy fleece that even boasts a little weather-resistance thanks to its DWR finish. So yeah, 'Tazan' kind of makes sense. And then we realized 'Peruvian' refers to the style, with earflaps built in to keep your ears toasty in wintry conditions. So we're going to stop quibbling and just enjoy this extra-cozy beanie.
