Summer Vibes is the second extended play by South Korean boy band Astro.

In June 2016, Fantagio Music reveals details for the second EP by rookie boy-group, Astro.

It is also described as a breezy, synth-pop track that continues the feel-good vibes from their debut single "Hide & Seek".

[1][3] The music video for "Breathless" was also released on July 1, featuring I.O.I member and label-mate, Choi Yoo-jung.

It shows the boys enjoying summer activities, as they appear to be human incarnations of soda bottles of the lead star.
