Spanish Translation help!

[btw1409]

Hola a todos!

I need a spot of help!

I saw this phrase in an advert in BA -

'es tomar sol todo el día ¿todavia no lo conocés?' (with a photo of someone sunbathing)

I understand all the individual words, but struggling to make sense of it - Google helpfully tells me it means ' is sunbathing all day long, do not you know yet?

Sorry, probably very simple and I'm having a mind blank!

Muchas gracias

Hello btw.

The translation is almost fine. The hard part could be the beggining: "es tomar...". It sounds unnatural to me because there's no reference to a particular subject, but it could be familiar among Argentinians. In Colombia, The form "eso de tomar..." sounds more natural

I would translate "Sunbathing..." or ·"That idea of sunbathing..."
