Bruce Jenner -- Dude Knows How to Chill

Bruce Jenner was out and about this weekend ... looking like his old self.

Bruce was leaving Starbucks in Westlake, near the family homestead in Calabasas. Even though Bruce and Kris have separated and he's planted his roots in Malibu, he's still spending lots of time with the fam.

He had just finished a round of golf ... part of his daily routine. And he's decked out in his standard golf issue.

BTW ... he's one of the best golfers at the Sherwood Country Club.
