This water bottle is great for me to take with me when I am working out. I can fill it up with quite a bit of water so it lasts me a long time. The grip on the outside makes it easy to hold onto even if I am sweating while working out. It fits well in my hand so it is easy to drink out of. The opening is also big enough I can easily put ice in it if I want to and my water stays cold for a long time. The spout is easy to open. All I have to do is twist the lid. I love that when I twist it shut, it seals so nothing leaks out. Even when I’ve dropped it on accident, it has stayed sealed. Since I have kids who are always knocking over my water bottle, the fact that it won’t leak when it is closed is my favorite feature.
