Issaquah-based business Combat Flip Flops appeared on ABC’s “Shark Tank” Friday night and its owners came home with a $300,000 investment.

The clothing business, founded by former U.S. Army Rangers Matthew Griffin and Donald Lee, sells sturdy casual wear repurposed from military clothing, equipment or weaponry.

The company’s Claymore bags are made in the U.S., but other items are made in conflict-ridden areas to generate jobs and foster economic security as an alternative to warfare. Sarongs are handmade by local women in Afghanistan and bracelets are made out of unexploded bombs in Laos. Combat Flip Flops’ eponymous footwear is made out of old military boots in Bogota, Colombia.

CEO Griffin, speaking at TEDxTacoma in March, said he first conceived of the idea after seeing the jobs generated by a combat boot factory in Afghanistan.

“It was amazing,” Griffin said. “They were supporting thousands of family members. They were supporting their community. They were helping defend their country.”

Friday night, Griffin and Lee initially sought a $150,000 investment for 10 percent equity. Two of the episode’s “sharks,” Mark Cuban and Daymond John, offered $200,000 for 25 percent equity but Griffin and Lee turned that offer down. They relented when Lori Greiner threw in her own stake to the deal, bringing the total investment to $300,000 for a 30 percent stake.

“It’s a good mission,” Greiner said.
