We've revised our best selling Lambswool beanie and made three major improvements. * New improved design * Higher wool content * Seamless / 3D knitting Seamless Lambswool Beanie 2.0 - Charcoal Tartan New Design This new design has been two years in the making. We measured many different head dimensions and obsessed over how tight or slack the rib structure should be. This gave us an improved shape that not only looks better but is far more comfortable. Relative to our 1.0 beanie the 2.0 contains over 50% more Lambswool. This increase in wool content gives an unparalleled premium feel that isn't found in the cheap acrylic ones you're going to see sold everywhere else.
