This is TECHNICAL Material and is similar style as our New Balance Short Sleeve V-neck ladies, but fits slightly snugger. I've had multiple members, who ordered this, exchange for the next size up. This is a more traditional tech shirt fit than our other long sleeve New Balance performance tech shirts that come in the Safety Green and Pink (those are more of a runners fit and fit a little snugger than these). Unfortunately this style does not come in our pink or safety green so we are offering the black with safety green logo, or the white with black logo for now. I highly suggest ordering up one size from your true size in this shirt.
