Wasnt reall y expecting it to work this good but holy crap

Hubby loved his pair! Getting another in his Cowboys Blue!

Spilled some beer on them and people freaked out. Now everyone wants a pair.

Perfect for a day on the boat. When you're hot they're 1 color, then when you cool off, they're a totally different pair of shorts. Came in like 4 days too.

My son absolutely loves his. Getting him some more colors for his birthday as a surprise!

Came fast, work well.

These were meant as a gift for my cousin but when I tested them out I had to keep them and order him another pair lol

When they start drying, they make a really cool tie-dye type of pattern.

My gf left this handprint

These are my favorite shorts now, hands down.

Best shorts ever made!!!!

I love these things

These shorts are hilarious.

These things are ridiculous but I love them

Got these as a joke but was surprised how well they work. Bought another pair.

Order arrived quick

I peed my pants in these and wasn’t embarrassed lol

these are great
