Great comfort, funny sizing

    This is a tough one to size. I literally wear a size large in every icebreaker item out there. I'm 6 ft 170 lbs. Seems this one I should have got a medium but in their measurements I'm clearly a large. Maybe buy both sizes and return one.

    Tad overpriced

      Cozy. Wool component minimal.

      Hey there Jeffrey,
      Sorry to hear you were not satisfied with the reversible Helix Flannel. One of the coolest things about the piece is not only is one side 100% pure merino, but there's actually a 70gm fill of Merino inside the recycled poly lining. If you're looking for a nice Merino shirt option that is lower in price but has a similar aesthetic, I'd check out our Lodge Flannel. Really warm shirt, great fit, 100% merino. Let me know if you have any questions about Icebreaker products in the future.
      Sincerely,
      Sydney
