Ive gone through a lot of insulated water bottles in my time and none have stood the test of time like the Rookie Bottle. I decided to give it a try on a warm day while out in town. It sat in my car when going in and out of stores. While my kids water bottles that are also insulated didnt quite hold up like Rookie Bottle. I love that it kept my ice frozen and my water literally ice cold, even in a hot car. I should also mention it comes with a straw, and a cleaner for the straw as well, which is always handy. It was well packaged and is dishwasher safe (top rack). Although it does recommend to hand wash. Overall this is the perfect size for on the go, at home, or even for your kids.
