Kourtney Kardashian & Kendall Jenner Soak Up Memorial Day By the Pool

Kourtney Kardashian and Kendall Jenner stuck to their guns on Memorial Day -- which, as far as we can tell, reads something like ... wetter is better.

The sisters posed for a photo together Monday, which showed them, Jordyn Woods and one of the Simi and Haze twins in their bathing suits ... and holding Super Soakers.

They definitely looked like a hot new posse of 4, rivaling some classic ones like the 'A-Team,' the 'SATC' gang ... or, hell, even the 'Golden Girls.' And then, suddenly, there were two -- namely, Kourt and Kendall striking floatie poses in the pool. Rear to rear, mind you.

Just goes to show that while there's strength in numbers ... nothing beats a dynamic duo.
