Ripple Junction will create a line of men’s and young men’s Mythbusters apparel which will include knit and woven, sleeveless, short-sleeve and long-sleeve t-shirts, hooded shirts, track jackets and hoodies. Launching this spring, the designs will be available at mass, mid-tier, department store chains, specialty and independent stores.

In addition, Sellers Publishing is developing a 12-month, page-a-day Mythbusters calendar, which will feature a myth from the show on each page. The 320-page 2013 calendar will be available this fall at mass, mid-tier, department store chains, bookstores, specialty and independent stores.

Its North-American licensing agent, the Joester Loria Group, brokered both deals on behalf of Discovery Communications.

For Sons of Guns, Discovery has signed Club Red for a Red Jacket Firearms branded apparel line, which will debut this month. The Sons of Guns line will be sold in regional retail stores and national retailers including Academy Sports and Outdoors and Bass Pro Shops. Star of the show and owner of Red Jacket Firearms, Will Hayden, will help launch the program, along with his daughter Stephanie who is also featured in the series.

“Sons of Guns has quickly become a hit for Discovery Channel,” says Elizabeth Bakacs, vice president of Discovery Channel licensing. “We are excited to develop a Sons of Guns line of apparel with Club Red, with their vast experience in the hunting and outdoor retail space. There are a breadth of opportunities with this brand and we look forward to building it with potential lines of accessories and more.”
