For many runners the season begins with the arrival of Fall. The comfortable Autumn air generally improves performance. But soon, there is something that can put a damper on one’s motivation. The coming of Winter and the cold! There’s no better test of a runner’s loyalty than a cold morning run. But with the Smooth Wool Long Sleeve T every Winter day feels like Fall. The frizz of wool (crimping) masterfully and naturally keeps the warm air in and the cold out.


  • Silky smooth to the touvh

    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.
