About Us

Jack & Mack tees is a classic lifestyle brand with a Massachusetts inspired twist. These tees are perfect for boating, beaching, dartying, and everything else in between. Hailing locally from the South Shore, our tees aim to bring fresh, new ideas to the tried and true.


We are bringing a whole new meaning to “business in the front, darty on the back” for our styled shirts.


Jack and Mack’s newest tee will be an ode to the Cape Cod town of Sandwich. Sandwich has been a special place for us, our family, and our friends for many years.


While Sandwich has been a fun destination for us, it has been a lifelong summer home for one of our closest friends, Brenden Teague. Our camping trips always center around the Teague's Sandwich home and it is a great time every year. After hearing about the heartbreaking loss of Justin Teague, Brenden's dad, we knew that we wanted to dedicate our Sandwich tee to the Teague family. The message, JT Strong, is a nod to Mr. Teague's brave 20 year battle with cancer and his accomplishments through the Pan-Mass Challenge. We added JT Strong under our logo on the pocket and the frame of the bike. The Teagues have been heavily involved with the PMC for years, and it was moving to learn more about their work. They have raised over a quarter of a million dollars and participate in the biking challenge every year.


With help and inspiration from Jean and Brenden Teague, we are donating all of the Sandwich shirt's profits to the December 5th, 2020 PMC Reimagined fundraiser. When we first proposed the idea to Brenden, he denied us giving up any profit and told us that the notion was outstanding enough; a surefire example of the humble kid that his father raised. The only thing more impressive that we have learned through this tragic time is the Teague family's resilience and humility. We have been inspired by Brenden's insight, strength, and maturity this past week. One thing that he has made clear is, life goes on. Brenden has proven to us that the Teagues never quit.

Thank you,

Jack and Mack
