The Big Jerm Collection

You knew he had the forehand, but did you know he has the design chops to match? Big Jerm played lead in designing his line of Tour Series Polos and Tees, and it really shows. They're bold, fluid, and catch the eye.
The Thomas Gilbert Collection

The Thomas Gilbert Collection

This guy is easy to root for. He has incredible disc golf talent; he makes outside the circle putts like it's nothing to him, and drives a disc like very, very few can. He's also Canadian, and a genuinely good dude. His design style is bold and playful, displaying his Canadian pride. We are proud to be working with him. 

Tour Series

Purchasing a Tour Series product is a fantastic way to support your favorite touring professional. A portion of the purchase goes directly to the player.
Warm Stuff

Warm Stuff

Sometimes you need a bit more than a polo to keep you comfortable out on the course. This casual warm gear is great for wearing around the house and for your non disc-golf outdoor pursuits as well.
