Supporting the lives of Veterans, Service Members, First Responders, & their Families
From the inception of DIA in 2021, my goal was to design and sell gear that helps spread the message that each and every single one of us already has what it takes to be great. The only thing that is required is Discipline, Intensity, and Action every day towards whatever you feel will make you great.
In addition to spreading the DIA message, I also wanted to give back to those who sacrifice so much. Because my business partner and I are United States Marine Corps Veterans, we understand the sacrifices service members and their families make in the support and protection of our country and it's citizens. We hold veterans in high regard because they wanted to be and have achieved greatness. Some service members even going as far as giving their lives for you and me.
In addition to supporting veterans and service members, we also feel that First Responders sacrifice so much for us as well. They put their safety and lives on the line every single day.
Therefore, DIA gives back by donating a percentage of proceeds from the sale of all DIA gear to organizations that support the lives of Veterans, Service Members, First Responders, & their Families. We know they sacrifice so much to help ensure our freedom and safety.
Organizations we've donated to since 2021 include:
- Flanders Fields
- Children of Fallen Patriots
- The Paddy Brown Foundation (Captain Paddy Brown was a USMC Vet)
- Operation Allies Refuge Foundation
- National Fallen Firefighters Foundation
Although we're still a startup, we know Veterans, Service Members, First Responders, & their Families need our help. And that's what we will continue to do: to help those that help keep us free and safe, even if we are unable to turn a profit. It just makes sense to us.
If you have any questions or know of good organizations that could use our help, please reach out.
Sincerely & Respectfully,
David @ DIA
Semper Fi!

I wear this hoodie in honor of Capt. Paddy Brown of for the men of Ladder 3

Love this hat!

His sacrifice saved so many! A true hero!

I was so impressed with my first DIA hoodie, I ordered two more! One for me (USMC Vet) and one for my daughter (USN Devil Doc). The quality of the hoodie is impeccable but what's even more important is the reminder to Never Forget the pain of the Benghazi & Kabul disasters.
Semper Fi. Never Forget.

Great quality. Arrived in a timely manner.

Ordered wrong size . So gave it to my neice. Will be ordering right size soon

Most importantly, I love the critical messages the shirts deliver. My shirt is in rememberance of the Kabul 13. In addition, the quality of the product is outstanding. My sweatshirt is warm and a little longer in the body than most. Customer service is also great. I had to upsize my sweatshirt and the staff made it super-easy.

From top to bottom left to right this company makes a great product and has superb customer service and availability. Can't go wrong with DIA

Second time ordering from DIA. The shirts sizing and material fit perfect, the graphics are top notch and supporting the cause of John Chapman and those Heroes that were listed in Benghazi is something I will never stop doing. Back a year or two ago I actually submitted a request to have the Chapman shirt reflect an Air Force Blue color in it. I received a message back from DIA that my suggestion would br considered and a few months later DIA sent another message that they were going to produce a Chapman shirt with the blue graphics. Not very often something like this happens but I am happy to own a few Chapman shirts now and they are treasured possessions to me. It is a pleasure to support a dedicated, Veteran owned company that gives back and supports our Heroes!! Well Done,

Excellent

High quality, high rate of customer service availability, personable, always looking to make something work for the customer. When it comes to dealing with typical companies in the world today, these people are a breath of fresh air. Someone got back to me at like 7pm. I was shocked. They also sent me an email to verify that I received the last one since they hadn't heard from me and wanted to check in on my return. Great stuff. You could really tell they strive to have a good product and satisfied customers. They cared.

This shirt fits great and it reminds me to be present in the here and now.

Shirt arrived in a timely manner, good quality shirt, love the the print!

Nothing should be changed but different colors of The Corps hoodie,keep up The Good work 💪. Very satisfied.

Great shirt honoring heroes
