Riley is an 18-ounce vacuum-insulated, double walled bottle designed to keep drinks cold for up to 24 hours. The unique removable base allows for easy cleaning while the push-button locking lid provides quick access to a comfortable silicone spout. The spout contains Guardian Technology™, an anti-microbial additive designed to keep the drink surface cleaner for longer. A soft-touch carry loop allows for easy transport and tucks away when not in use.
