Our mulesing free Merino ½ Zip Tee is designed with winter in mind and is our product of choice to layer up with under your jacket. This tee features Tech Merino - our premium 50/50 merino and polyester blend that offers numerous benefits. Runners go through many highs and lows during a long run and one of them will be your body temperature. Merino has a unique quality, which will help lower your temperature when you start to overheat and warm you up when your temperature is low. To put this to test we handed this over to our ambassador in Canada who ran over 200km in Winnipeg and Cold Lake in temperatures ranging from +5c to -27c. The feedback was that in the colder temperatures it was a perfect layering piece with the Stride Winter Gilet or an Infinity Fortify jacket. Our sub-zero hero said that the tech merino was “very likely the best winter running top that I have ever worn”. Merino isn’t just about temperature regulation. The natural fibres of the wool are smoother and finer than others making it soft next to the skin. Merino has the additional benefit of being anti-microbial which makes it odour resistant. Additionally our Tech Merino has higher strength and increased abrasion resistance for better durability.
