The rockers were surfing off the coast of Carolina Beach in North Carolina on Wednesday (08Jun16) when they heard four boys - aged 12 to 15 - screaming for help.
The kids were struggling to get out of a rip current that had dragged them 100 yards out to sea, TMZ.com reports. Stephan and Brad paddled out to the boys and let them rest on their surfboards, before bringing them back safely to shore.
Luke MCNees, manager of Third Eye Blind, told the website that other than being winded and scared, the boys were uninjured and very grateful to the rockers who saved them.
The band confirmed the rescue on Twitter on Thursday (09Jun16), and revealed that the rockers were surfing during a break from rehearsals for the Bonnaroo Music Festival. "On a surf break during rehearsals for #Bonnaroo @stephanjenkins saved a boy being swept out in a rip current," they wrote alongside a photo of the frontman and one of the boys paddling safely to shore.
Stephan later retweeted their post on Thursday and wrote, "And I got my back sunburned. Moral of this story is always wear a rash guard...Or is it beware of rip currents...er (sic)."
The Bonnaroo Music Festival takes place from 9 to 12 June (16) in Manchester, Tennessee. This year's line-up features performances from Pearl Jam, LCD Soundsystem and Ellie Goulding.
