With an iconic shape, the slim design makes it easy to pack. The All Day Slim Bottle from Stanley uniquely opens at the shoulder so you can fill it up with ice and stay refreshed. Just give the collar a few twists to shut for a leakproof seal and uncap whenever you need a drink. Stainless steel construction provides ice-cold sips for hours. Whether it lives next to your beach tote, or becomes your in-flight favorite, keep hydration simple.
