The design of the GoGrow bottle is sleek and immediately caught our tester’s attention as something innovative and “cool”. The metallic outer casing with rubber grips are not only slick looking but easy to grab and hold for both baby and parent. The bottle has a matching cap that clicks on and off very easily. The inside of the bottle is marked for measuring ease, those marks are easy to find and read. Parents felt it was perfect for getting exact measurements for formula, milk or whatever you’d need to keep cool. The GoGrow bottle washes easily with either a hand brush (soap and water) or in the dishwasher (top rack). The bottle is surprisingly lightweight compared to other thermos-like bottles which results in lighter loads, including your diaper bag. Parents were sure that an insulated bottle that so effectively keeps liquids cold, was lightweight and easy to hold would be a worthwhile purchase they would make and would be recommending to others.
