Here's what other sites are saying:
The fitted Sugoi Carbon T-shirt performs well as a warm base layer or cool weather running top for year-round exertion.
Articulated sleeves, carbon-infused fibers, and moisture-controlling fabric are what make this Sugoi Men's Carbon Shirt ideal for running and other high-output activities. The fact that you can sport it on its own on a cool fall run and a high-elevation hike in summer, and wear it as a base when you brave bitter winter on the slopes, is what makes it special.
