The ALRN Cross Back Bra is made from post consumer waste products  ( including fishing nets and carpets) and is sustainably produced in a method that significantly reduces water usage. This style has been re-fabricated and is now offered in a lightly compressive double knit for the perfect amount of support, stretch, and comfort. The open back design allows for breathability so you can move freely in a sports bra that is also good for the planet.
