Lululemon | High Neck Split Hem Run Tank Black | Size Medium. This tank is in excellent condition. The tags have been taken off so I sized it based on the pit pit measurement. See chart in pictures. This is a very stretchy tank. Added additional PTP measurement for stretch. Keep cool when the intensity heats up. Overlapped side seams on this lightweight tank offer airflow and room to move, just like a classic running short. Sweat-Wicking Fabric Sweat-wicking Four-way stretch Added Lycra® fibre for stretch and shape retention Please see pictures for measurements. 8
