The Turtle Fur Aleah Beanie uses a wool blend to deliver real warmth without the bulk of a heavier knit. A mix of recycled polyester, nylon, wool, and spandex gives the knit its stretch and shape, while a micro fleece lining made from 100% recycled polyester adds a soft layer against the scalp. Both the face fabric and lining carry confirmed recycled content, not just one or the other. What Our Gearhead(R) Experts Are Saying:"I packed this instead of my usual thick beanie for a weekend trip, worried it would be too light for actual cold, and it kept up through a full day outside without my head ever feeling exposed. It packs down small enough that I almost forgot it was in my bag."
