I Love 13.1 V
Performance weight fabric; Longer 26″ body length; Lifestyle Fit; Anti-odor technology; UPF 50+ Protection; All performance attributes are inherent to the fabric and do not wash out! (55% Organic Cotton/40% Viscose from Bamboo/5% Elastane)
This is the perfect T, if it is clean I am wearing it. It is so soft and comfortable. I have a Medium and it fits pretty true to size.
I Love this shirt. I can workout & run in it or throw on with some shorts or jeans and wear out.
