The Difference

Thoughtful Fabric: Siro Micro Modal, the fabric selected for the Beau Bra, is an environmentally friendly, sustainably produced fabric known for being extremely smooth, soft, and cool to the touch. The fabric is resistant to shrinkage, fading, and hard water deposits (so it stays soft). It’s also extremely breathable, excellent at absorbing moisture, and shows minimal pilling. The 5% spandex allows freedom of movement without bunching.

Intelligent Design: Our T- back design keeps straps from twisting to prevent awkward malfunctions.
