Classic cable knit design combined with the functionality of a waterproof hat. Our AQUASEALZ ® three-layer waterproof and breathable construction will ensure that you're not only warm on your daily adventures, but also well protected from snow and rain. Complete with a micro-fleece liner for warmth and an EcoTeflon coating so that water beads up on the face of the hat. Ecolite Teflon is a renewably sourced, plant-based, non-fluorinated fabric repellent that meets a 30-wash durability. A true biobased product. Machine-washable.
