This Smartwool beanie offers all the benefits of responsibly sourced Merino wool for comfort, as well as the durability of recycled polyester. It’s constructed in two layers, so it offers extra warmth. And if your day takes you out on the slopes, this beanie will fit nicely under a helmet. Plus, it’s reversible, so it’s like having two hats in one. Please note that this hat is quite roomy; in our store, it's been best suited to men and women with thick hair!
