Talk about a fatherly sacrifice — Ben Affleck’s keeping the superhero fantasy alive for his son Samuel … despite hating every second spent sweating it out in the Batsuit.

Check out the pics — Ben and his 13-year-old son were out on Easter Sunday hitting up BAIT boutique in L.A., where the actor was spotted loading a DC Batman Hush figure, which retails for just over $400, into his car.

Looks like Samuel, Ben’s son with ex-wife Jennifer Garner, was getting the royal treatment — ’cause before their toy shopping spree, the father-son duo also made a pit stop at World Market.

The “Justice League” actor was juggling a mountain of shopping bags as he and his son emerged from the international specialty store, both looking like they were having a blast.

Ben, especially, seemed to be soaking up the sunshine, and there was no sign of sweat in sight — unlike when he was rocking that skintight Batsuit on movie sets, which he said had him pouring sweat.
