KUNG HEI FAT BOY

We wanted to celebrate the awesome bouldering problems in Hong Kong, so we named Fat Boy Chunky Chalk after the famous Shek O classic, Kung Hei Fat Boy (sds) V6.

Start sitting on the right corner of this large boulder and use big, powerful moves up the variety of cracks and crimps and make your way up to the top!
