Smooth wool keeps your neck warm.


  • The neck is the confluence of lymphatic vessels. Warming this area improves the flow of lymphatic fluid and muscle movement. The neck is also a sensitive area.
    Therefore, natural wool is the perfect material to warm this area. Moreover, SMOOTH WOOL NECK WARMER is knitted with the same 17.5 micron ultrafine yarn as HERENESS standard item, the SMOOTH WOOL T-SHIRT, so it will warm your neck softly without stinging.
    The wool also has a deodorant effect, so it won't leave a bad smell even if you pull it up to your mouth. This neck warmer will give you the push you need to run in the winter.

    Wool is also amazing for its odor resistance. That means your wool garments need less frequent washing, reducing your water and energy consumption. With less need for laundry, wool is also a great option for traveling and enables you to travel light.

  • Why non-mulesed merino wool?

    New Zealand has decided to ban mulesing (the process of removing skin from sheep buttocks), and the wool we use is 100% sourced from Merino sheep in New Zealand. We believe that wool is a gift from sheep, and we should not support any practices that result in their suffering. As a brand promoting the benefits of wool, we are committed to advocating for animal welfare.
