Scott Disick with son Mason on Aug. 4
It's a guys-only trip to the beach!
Scott Disick took his son Mason, 2 ½, out for some sun, sand and surf in Malibu on Saturday.
The father-son duo – one in navy trunks and the other in a diaper! – looked happy as clams as they played in the water and bundled up in beach towels.
Mom, Kourtney Kardashian
, is nowhere to be seen but she's likely at home with Mason's little sister, Penelope Scotland, born July 8
And it seems the beachgoers ended the day totally tuckered out: "Had a great day in malibu," , "now the lord is off to sleep."
