Lululemon Somatic Short Sleeve Black

I believe this is the Somatic Short Sleeve, but a newer version than shown in the stock photo. The only difference I see between the one I'm selling and the one I'm selling has the newer logo. Reflective stripe down the back. Last photo shows the inside of the shirt. I believe this is an XL, but it's possible it's a L. Please check the measurements. Pit-to-pit is approximately 21".
