From the site: “To create this loose-fitting, light and airy tank we used a combination of sweat-wicking Luon in the bra and lightweight Mesh in the core to optimize its movement and breathability. It's the perfect match for our Vinyasa practice where we like our clothes to mimic and accentuate our flow.” This tank is great for yoga. It’s a loose fit but the body is moisture wicking, great for a good sweat. No bra cups. Size 10 EUC
