You've heard of cotton, hemp, and bamboo fabrics and more…. But have you heard about yak? The Glencoe Striped Tank Top by United by Blue utilizes breathable and naturally antimicrobial yak fibers in a seriously stylish way. By blending it with organic cotton and hemp, they've created a soft, lightweight tank with an A-line swing silhouette to compliment any shape. With feminine details like a back keyhole neck closure and modest crew neckline, you may be wearing yak, but you'll feel like a queen.
