I am very comfortable that container, I often take with them something of salad type of fruit or vegetable sticks, yogurt with granola. Super, that can be divided into a snack: salad dressing separately to the salad does not mock, but still fresh, yoghurt muesli separately, so as not to soaked, dip in a separate jar, it was convenient to dip vegetable sticks. Cooling unit - a very good idea for the summer. Lower container volume of 470 ml, the upper - 118 ml. The bag stands convenient because narrow. Carbine was not useful to me yet but it's nice that such details are provided.
