American band Echosmith has teamed up with clothing brand Hollister to feature in its 2015 anti-bullying campaign, All Equal.

The brand has also designed a line of t-shirts featuring inspirational messaging to help raise awareness around anti-bullying. Sydney Sierota, lead singer of Echosmith, commented 'Most people struggle to fit in and feel like outsiders at some point in their lives, which is why we joined this campaign and what inspired our song Cool Kids. Anti-bullying is a cause that's close to our hearts and we're excited to work with Hollister to raise awareness around this important issue'.
