The switch

A little colour.A lot of summer.

Every pair is printed with a thermochromic pigment, so it shifts shade as it warms up in the sun, then switches back when you dive into cool water. No two swims look quite the same.

If I had a dollar for every time a person who asked where I got these I would buy another pair lol

These are literally the coolest pair of board shorts that I’ve ever bought. My kids love pouring hot and cold water on them and watching the colors change.

Love these trunks! I wear a 38 in jeans so I ordered the XL and they fit great! I also love that the drawstring goes all the way around your waist (instead of just being tied in the front) so that they actually stay on when you jump out of the pool quickly.

I got these swim shorts for my pops. He is a relatively big guy at 6'2". The large fit him good and weren't too short. They hit right above the knee. Some shorts look so goofy on him so I was pleasantly surprised how these fit They stayed on while swimming and going down waterslides!
Kim
So freaking cool! I didn't know if they really worked as well as the ads showed but wow im impressed

I was skeptical about buying a swim suit online without trying it on, but took the leap because of all the positive reviews, and I needed a new suit for a trip to Florida. I must say that I love this suit. We swam every day for over a week, and the suit fits great and caught so many peoples attention.

Purchased for my 20-year-old Grandson and he lives in these shorts. He loves the fit, the material, the pockets. Well made and a good price. He lives in the Tampa area so these are worn practically year around. Paired with a dri fit t-shirt he is good to go! A nice variety of colors are available and shipping was quick. He likes the pockets also. He is 32 in the waist I purchased the Medium and the fit is perfect.

I bought these for my boyfriend as a birthday present and I cant wait for him to use them and see they they are not just typical swim shorts haha
PJ
