From the tops of mountains to nestled in your sleeping bag, it’s amazing how much warmer you feel with a woolly hat pulled down over your ears.

Made using 100% sheep’s wool in a ridge knit, the Roag is half-lined with microfleece for a soft feel against your skin. Nature’s great insulator, wool makes a great material for keeping your noggin warm. Plus, it’s highly breathable and odour resistant, so you can wear it more and wash it less.

Each bobble hat from Black Yak is hand-knitted in Nepal. As well as being certified fair trade, a proportion of Black Yak’s sales go back into the communities that make them.
