This is the long sleeve Heattech T-shirt that I personally recommend as innerwear or a top for the chilly days! It’s lightweight but not see through! Very stretchy, and helps retain heat. Approx. Flat Measurements: • Pit to Pit: 15” • Pit to Cuff: 18.25” • Waist: 13.75” • Length: 24” Condition: NWOT, no original bag or packaging
