Tieback Short Sleeve Shirt $45.00 Made in El Salvador. A twist on a traditional t-shirt, our Tieback Short Sleeve Shirt features a cap sleeve and an opening in back. The back is perfect for highlighting a fun sports bra while still providing coverage. Tieback can be tied for playful interest or left untied for more coverage. Our bamboo fabric is super soft, while the elastane spandex in the fabric allows for just the right amount stretch.
