It was time to "give back" last weekend on O'ahu's North Shore.

Two events completed on Sunday involved surf-related companies helping out the surfing community.

At Turtle Bay, around 140 youth surfers got to compete for free at the Oakley Big Day Out contest. Oakley, which is a sunglasses and clothing company, covered the entry fees and provided lunch for all the competitors.

"The industry is getting younger and these are the surfers who will continue to support the brand," Oakley sales representative Jason Sakamoto said. "Basically, it's a thing that Oakley does nationally to give back to the industry."

There was also an Oakley Big Day Out contest at Kewalo Basin in July.

"We wanted to do one in town and one on the North Shore to give all the kids a chance," Sakamoto said. "It's something we want to do every year."

Farther along the North Shore, more than 200 people participated in the inaugural Da Hui/Wolfpak North Shore Beach Clean Up.

"We didn't just clean the beach, we did the road and the bike path, too," Wolfpak spokesman and professional surfer Kala Alexander said. "There are a lot of people who live here and work here, and they don't like the pro contests because of the litter and the traffic. So we wanted to show the community that the surfers do care about this place."

Several other professional surfers participated in the clean-up, including Andy Irons, Bruce Irons, Makua Rothman and Myles Padaca.

The clean-up covered a four- to five-mile stretch, from Ke Iki Beach to Velzyland. Alexander said he would like to extend it to Hale'iwa next year.

"We got the beach clean, that's the main thing," he said. "Now we need to keep it that way."
