DetailsIslay Hill Tank Size Chart Islay Hill sits right on the edge of San Luis Obispo and is a popular lunch time trail run due to its convenient location, manageable distance, and breathtaking panoramic views of the Santa Lucia Mountains and the Edna Valley wine region. CIRQ’s Islay Hill Tank was designed for sunny and hot California mid-day runs. The lightweight, quick-dry, cool-to-the touch fabric keeps you comfortable when the trail starts to get steep. The dropped armhole and high neckline provide both ventilation and sun protection where it’s needed most and looks great layered over your favorite sports bra. The drop-tail hem with contrast stitching and reflective logo hit make for a truly flattering summer tank.
