Soft merino wool blend knit beanie, fully lined with the same knit for extra warmth.This Reima beanie is rich in wool, which is still warm when moist, so even if your kid breaks a sweat, the beanie won't chill them. Wool is naturally dirt-repellent, so you can wash less - and for maximum ease, it's machine washable, just like all our beanies. The recycled polyester in the blend helps the material wick moisture, last longer, and dry more quickly. We made the beanie Responsible Wool Standard certified wool, to make sure that both the sheep and their pastures are treated well.
