While most of us are battling sand in unfortunate places or melting in city heat, Zac and Dylan Efron are living their best lives on a lakeside getaway thats basically a Pinterest board of Summer Goals. And yes, the shirts were left at home.On July 1, Zac Efron, 37, made waves (literally) on Instagram by dropping a carousel of lakeside pics that instantly reminded the world why hes still a gay heartthrob. No caption, no explanation, just vibes. The post opened with the High School Musical alum shirtless behind the wheel of a boat like some kind of nautical dream, followed by a shot of him wakesurfing like a pro.Another snap showed Zac strolling solo with only a towel wrapped around his waist, casually looking like an Abercrombie ad. The post ended with an adorable sunset video of him and his younger brother, Dylan, trading cowboy hats while floating on the boat.Dylan Efrons POV: Shirtless, Sunny, and Sponsored?Dylan, 33, gave his followers a sneak peek at the fun a day earlier, posting a video montage of the lakeside hangout. His Instagram video opened with the text Describe summer in one word, set to the breezy Briscoe track Easy Does It. His answer? This.The video shows the brothers taking turns launching themselves off a dock into the water, wearing only swim trunks, and presumably a brand deal, as Dylan tagged Vuori in both the caption and the clip.Also making an appearance: Dylans longtime girlfriend Courtney King, who got tossed into the water by her man like a true lakeside rite of passage. (Cute aggression is real.)Cowboy Hats and Hero MomentsWhile the brotherly bonding and ab-filled photos stole the spotlight this week, Dylan recently reminded fans hes more than just pretty abs and a middle-part haircut. During an April episode of Brooke & Connor Make a Podcast, the Traitors star recounted a surprisingly dramatic story from his first visit to Miamis South Beach.I walk up to the shore for the first time ever, and Im looking out and it was just people screaming in the water, Dylan recalled. He, actor Sam Asghari, and their friend Brandon ended up rescuing several girls who were caught in a rip current. Dylan brushed it off with a shrug, calling it random, but honestly? Hes a certified lifeguard in our hearts.After the group was safe, Dylan simply hugged one of the girls, said youre safe, and walked off like a shirtless superhero with no need for applause. Iconic.A Little Brotherly Thirst This Holiday WeekendWhether theyre goofing off in cowboy hats, saving lives on the beach, or just giving the gays everything they want via Instagram, the Efron brothers continue to deliver. Their Fourth of July-week energy is peak summer fun, wholesome, hot, and hilariously low-effort.Source
