The US women's soccer team is amplifying its message for equal pay with a new tactic: press conference t-shirts with the slogan "Equal Play Equal Pay" and temporary tattoos with the same words that can be worn on the field. 

Over the past few years, the team has become one of the staunchest champions of equal pay for women, a cause that has reverberated throughout the US.

After they won the 2014 FIFA World Cup, it was revealed that the team earned 17 times less than its counterpart in the men's league, the German team. They also made four times less than their US counterparts, who came in 11th place. 

Off the international stage, the pay gap is even wider. For instance, women in the National Women’s Soccer League earn 98.6 percent less than men in Major League Soccer.

Recently, the US women's team faced setbacks in more official quarters — the courtroom and the negotiating table — and so they're hoping to revive the cause as the Olympics approach in Rio. 

The jerseys and tattoos will make their message unavoidable. The players will also use their considerable social media followings to blast the message ever further.

All around the world, women are exploited and paid less than men. The US women's soccer team has enormous reach. By universalizing their cause with a simple hashtag, they're able to fight for women everywhere.
