When we're moving and flowing in yoga class, we need a tank that will match our pace. We designed this light-support tank with a high neckline and an adjustable, strappy back to help keep our girls in check from Chaturanga to Savasana. cottony-soft Luon fabric engineered for serious stretch and recovery, sweat-wicking, four-way stretch, breathable strappy, open back design gives you freedom to move and twist, slide the shoulder straps out to adjust the fit and feeling of support.
