Lululemon White Twist and Reach Mock Teck Yoga Workout Tank | Size M

I THINK this is the Twist and Reach Mock Neck Tank. There is no style number on the tank. Twist and flow freely through your practice in this tank that we designed to make you feel cool and confident. The mock neck provides coverage where you want it most, while the back hem curves upwards to allow airflow and movement for your back and core. Fabric is lightweight, sweat-wicking, and quick-drying lightweight sweat-wicking quick-drying Features Designed for: Yoga Lycra®: Added Lycra® fibre for stretch and shape retention Relaxed fit: Gives you room to move without restriction Shorter in the back: Shorter hem in the back for distraction-free lunges and squats Ventilation: Back vent strategically placed to provide airflow Fits like a medium, i believe. Shoulders:n 14" pit-to-pit: 15" (but the arm holes are 11" from should to pit, so it's not at the widest point of the chest) shoulder to hem: 21" stretchy!
