Well I'm drinking out of one now, and coke cans are way smaller than this, so tiny isn't the adjective I'd pick.

Doubt you're walking around with a gallon jug in your backpack either.

Most beverages are sold in 0.5L to 1L bottles (a wine bottle is 0.75L), so "those tiny bottles" make the most sense when we're talking about a bottled water company.

I carry around 1 liter bottles, which is about the smallest before ‘consume in one gulp’. But I do drink a lot of water.

Sure, 0.5L is a small bottle, 1L is medium, 2L is large.

I feel like tiny sounds a bit too sarcastic though.
