We wanted to make the best wool t-shirt for running. That was our starting point. Wool, despite being a natural material, has a lot of great features. Wool's frizziness (crimping) lets in a lot of air and creates a layer of insulation. So it keeps out the cold in winter and the heat in summer. Plus, wool's "moisture wicking properties" are also remarkable. It absorbs up to 35% of the fabric's weight in water. Wool's "moisture absorption and desorption" regulates the runner's body temperature and keeps one comfortable throughout the entire run.


  • Silky smooth to the touch

    Many runners know wool is good for the body as well s the planet. But still have a negative impression of its feel. With a single touch of this ‘Smooth Wool T’ woven with 17.5 micron, the finest yarn available for apparel, these jersey t-shirts feel like silk. Once you put it on, you’ll have a hard time wanting to take it off, so may be good to buy two.

Sustainability Initiatives

  • wool-T in the room
  • non-mulesing merino wool
  • Cleanliness is directly related to environmental protection

    One of the main features of wool is its ability to prevent odors. There are many theories as to why this is so, but experience has shown that it is hard to smell even after a few days of normal wear. When you travel, this is an advantage in choosing your wardrobe because it reduces the need for washing. Also, reducing the number of launderings directly translates to reducing your environmental impact. Incorporate wool into your everyday clothing and try to reduce the number of times you have to do laundry? You’ll stay clean and also help in making the planet a cleaner place.

  • The Choice of Non-Mule Merino Wool

    Wool is a gift from sheep to humans. If the sheep who’s fleece we wear on our back were suffering, then the wool wouldn’t be a gift but rather a form of torture. Fortunately, all the wool we use in this t-shirt is New Zealand Merino wool. New Zealand has a national ban on mulesing (the process of cutting off the buttocks of sheep). The end result: happy sheep and happy runners. HERENESS will continue to address animal welfare issues on an ongoing basis.
