This is good for commuters or active people. I've tossed it in my bag, on the seat of my car..etc and no leaks at all. I tend to drink more water when I have a straw, so I like the flip lid with the straw. The handle makes it easy to carry and it's light enough to carry on a hike. It easily fits in my car's cupholders and the side pocket of my backpack that is intended for water bottles. The only downside is it recommends handwashing to preserve the vacuum seal.
