Prince Harry is back on the polo field.

The Duke of Sussex made an appearance on Thursday in Aspen, Colorado for the Sentebale charity polo match and confirmed he would be making a large donation to the organization he co-founded in 2006. 

Harry announced he would be donating $1.5 million of his memoir proceeds to the charity.

"This is one of several donations I plan to make to charitable organizations and I'm grateful to be able to give back in this way for the children and communities who gravely need it," he said in a statement according to royal correspondent Omid Scobie.

A rep for the 36-year-old confirmed to Fox News that his memoir with Penguin Random House will be published in late 2022.

"I’m writing this not as the prince I was born but as the man I have become. I’ve worn many hats over the years, both literally and figuratively, and my hope is that in telling my story — the highs and lows, the mistakes, the lessons learned — I can help show that no matter where we come from, we have more in common than we think," he said in a press release. "I’m deeply grateful for the opportunity to share what I’ve learned over the course of my life so far and excited for people to read a firsthand account of my life that’s accurate and wholly truthful."

The memoir will cover the British royal family member's life in the public eye beginning from his childhood to the present day.
