In this age of paid product reviews on Amazon and Yelp, it’s difficult to know whose opinion you can trust when it comes to making your next purchase. That’s where Emmy-nominated comedy writer Ethan T. Berlin comes in. He and his crack team of product reviewers relentlessly test all the latest tech equipment to insure that it does exactly what you would never use it for.

On this installment of Ethan’s Tech Buffet, the team looks at The Cavalier hydrophobic t-shirts, which are purportedly water-repellent. They’re made by Threadsmiths, an Australian company, who generously sent Ethan three complimentary shirts: A white men's XXL ($55), a black men's medium (also $55), and a white toddler-sized ($25).

“I didn’t try the toddler shirt on anything but a turkey,” Ethan tells us. “But the other two ran smaller than a normal t-shirt.”

How does the science work? David Mason, a spokesperson for Threadsmiths, told Ethan something about “hydrophobic nanotechnology” and “microscopic ‘whiskers’ that are closer together than a water molecule,” and it sounds really complicated and scientific.

“I had no idea what that meant,” Ethan tells us. “So I chose to think of them as magic.”
