In Uruguay and in the northeast of Argentina it is not uncommon to see people walking around the streets toting a "mate" and a thermos with hot water. In Montevideo, Uruguay’s capital, it is possible to see some construction worker drinking mate while riding his bicycle early in the morning, on his way to work. In some parts of Argentina, gas stations sponsored by "yerba mate" producers provide free hot water to travellers, specifically for the purpose of drinking during the journey. There are disposable mate sets with a plastic mate and bombilla, and sets with a thermos flask and stacking containers for the yerba and sugar inside a fitted case.
