In the latest travel craze, scuba divers have waved goodbye to their wetsuits.
This quirky ritual is encouraged for those who are taking their 100th trip under the sea.
In a recent post for Get Naked Australia, a tourist revealed what this is really like.
After taking a dip in the Great Barrier Reef, the adventurous woman wrote about how liberating it felt.
The Instagrammer said: “Its a tradition to do your 100th scuba dive naked.
“I was fortunate enough to be on the Great Barrier Reef in the height of stinger season when I reached my 100th dive!
“Two of my friends had surpassed their 100th dive but never got a chance to do their nude dive, so they were brave enough to join me for my 100th Dive.
“Most liberating experience! All 3 of us made it out without any jellyfish stings!”
A quick scan of Instagram shows that the ladies arent the only ones to enjoy a spot of naked diving.
Another image shows a bare bloke swimming in Koh Tao, off the coast of Thailand.
He captioned the picture: “Turns out naked diving is awesome.
“I wish I could naked dive every day.”
Another popular hotspot seems to be Dauin Beach, which is located in Philippines.
