Naked Zip Line For Charity In British Columbia (WATCH)

We know people can go to extremes for charity -- but would you go naked across a zip line to raise funds for a cause you believed in?

Eighty-four women gathered at ZipZone Adventure Park outside Kelowna, BC to raise funds for breast cancer research this week, reports The caveat? They had to zip across the canyon topless -- and ladies were lining up to do it.

"I'm okay with being naked -- if someone can face breast cancer bravely, we can face a little bit .. of nudity," says one of the participants in the video, before adding with a laugh, "Just don't let my mom and dad see it, okay?"

The event started in 2011, when a roller derby group asked if they could have a naked zip line and raise money for the Canadian Breast Cancer Foundation, according to AM1150 -- their event donated $1,500 to the cause.

This year, ZipZone owner Kevin Bennett took matters into his own hands and created spots for 100 women, with a minimum $100 donation to breast cancer. Though only 84 turned out -- including a 73-year-old woman who is a 24-year breast cancer survivor -- they raised $15,000 for the Canadian Breast Cancer Research Foundation.

Donations to breast cancer in honour of the event can be made at the CBCF's website -- or send a cheque to the charity at ZipZone, at Box 1064, Peachland, BC, V0H 1X0.
