We thought it was time for our beanies to get a serious upgrade. We've ditched the standard acrylic for 40 MIL merino wool. The merino will keep you warmer and drier than any of your other synthetic beanies-- it's impossible for synthetics to keep up with mother nature's finest. Custom knitted at America's oldest knitting mill, a family-owned, WRAP-certified business founded in 1926 on the New Jersey side of the Delaware River.
