I picked up the Stay-Chill Slim Can Cooler in Peony and it does what it promises. My seltzer stays cold much longer than in a plain koozie, and the screw top lid keeps the can secure. The double-walled vacuum insulation really makes a difference on warm afternoons. The ergonomic grip and non-skid base are nice touches. It fits 12 oz. slim cans perfectly. Only downside is hand wash only, but that's easy enough. The peony color is fun and stands out.
