Burton products, Burton stores sell several sub-brands which focus on specific market niches. These sub-brands include Anon Optics (snowboard goggles and eyewear), RED (helmets and body armor), Analog (outerwear), and Gravis (footwear, now defunct). In 2005, Four Star Distribution sold four of its snowboard brands to Burton: Forum Snowboarding, Jeenyus, Foursquare, and Special Blend. Burton also owned surfboard manufacturer Channel Islands, but sold the brand in 2020. The Burton line is split into four categories: freeride, for a big mountain ride; freestyle, for a versatile ride; park, for freestyle disciplines such as half-pipe and slopestyle; and carving, for carving down the sides of mountains. Each of these categories has different levels of performance and price. In 2009, Burton's line included 61 snowboards in men's, women's, and youth models. Board prices range from $300 to $1,500. In February 2008, Burton acquired DNA Distribution, which includes the skateboard brands Alien Workshop, Habitat Skateboards, and Reflex. In 2008, the snowboard equipment industry had grown to be worth $487 million. Burton had 40% to 70% of these sales, depending on the category. The average age of employees was 30.

Burton's sponsored professional snowboard team includes: Zeb Powell, Mark McMorris, Taylor Gold, Shaun White, Jeremy Jones, Kazuhiro Kokubo, Terje Haakonsen, Ellery Hollingsworth, Kelly Clark, Hannah Teter, and Kevin Pearce. Burton has avoided having complete sponsorship with Burton/Burton affiliated brands. Burton has come under criticism over its choices regarding team members, such as the removal of David Carrier Porcheron and other riders in 2008. Burton sponsored the creation of organic terrain parks made of rocks, stumps, and logs. These parks, known as "The Stash" can be found at Northstar, California; Truckee, California; Jackson Hole, Wyoming; Killington Ski Resort, Vermont; Avoriaz, France; and The Remarkables, New Zealand. Burton created the Chill program in 1995, to provide children with the opportunity to learn how to snowboard. Since its founding, Chill has provided over 12,000 underprivileged children the opportunity to learn how to snowboard. Because of the 2008 graphics controversy and concern over its effect on youth, a local beneficiary severed its ties with Burton. Burton created the Learn to Ride program in 1998. It was the only snowboard company to focus on instruction methods and beginner-specific equipment. Its goal was to give beginner snowboarders the best initial snowboarding experience possible, so they would continue
