This thermal 16 oz. bottle is made of double-wall, 18/8 stainless steel outer and vacuum-insulated copper interior. Also featuring a stainless steel threaded lid and strainer, the bottle keeps your cold or hot drinks just the way they should be. The strainer retains ice, fruit and large tea leaves, and can be used as a mixing shaker. But the best part? An oversized SD paw logo, front and center. Hand wash only. All purchases made at Charlie's support USD student scholarships.
