No doubt Austin Dillon has received a variety of gifts since winning his first Monster Energy NASCAR Cup Series race at the Coca-Cola 600 over Memorial Day weekend. But this one might be the best.

Tuesday, Dillon wrote on Instagram that he received a package in the mail, which contained a pair of old gloves and a letter from Lt. Col. Philip Pearsall in the U.S. Air Force. The letter introduced Pearsall as a huge fan of Dillon’s and congratulated him.

He also described the gloves and explained their significance, noting that he wore them for “every single combat mission I flew over Iraq and Afghanistan from 2003-2006 in the KC-10 air refueling aircraft that I piloted.”

In the letter, Pearsall continued:

“The reason I am giving them to you is simple…it represents sacrifice, sweat, dedication and hard work. All of these things are exactly what led you to your inevitable first Cup Series Win. So, I’d like to offer you a trade. My gloves for yours. I’m not asking for your race win gloves but I have a Dow driver’s suit of yours that I won during your 3-on-3 auction last year and I’d love to have some gloves or shoes to hang in my office with the suit.

“If this doesn’t work out, keep the gloves as a reminder of those who are serving and away from their families…understand what they represent. …”

In his caption of the photos he posted on Instagram, Dillon was clearly touched, calling the gloves “(o)ne of the coolest things” he’s ever received.

“It’s so awesome knowing that our true heroes that defend our country are the biggest @nascar fans. My gloves are headed your way my friend.”
