I love the design and fit of this jersey. The fabric feels great and is really light and breathable. The pockets on the back are more aero than any of my other jerseys. The color looks a little more purple in person than the photos on the website and fits true to size. I would highly recommend this jersey for any cyclist!

"As a former member fo the US National Team, I've had the opportunity to test a wide range of endurance apparel. Mach Apparel stands out to me in regards to it's comfort and breathability which allows the athlete to hold up better and have that extra freshness to surpass previous barriers."
Most "anti-microbial" fabrics only have a weak passive barrier against odor causing contaminants. Mach's DR711TM treatment actively absorbs and kills 99.9% of all microbes and bacteria that contacts it within eight hours. Mach's DR711TM treated fabric will stay odor-free, clean, and pleasant to wear through intense training and extreme use.
