In this video Shawn Mendes and his friend take part in the polar plunge by stripping down to their underwear and diving into freezing cold water. The polar plunge is an event held in the winter where people enter freezing cold water for charity or for fun.

This event takes place all over the world and now Shawn Mendes is joining in. As a pop singer hailing from Canada, he’s used to the cold (as you can see by his ice bucket challenge video). Let’s hope Shawn makes this an annual event.
