Take YETI®'s stellar name and quality anywhere - even the wild waters. The Rambler® bottle comes with the same double-walled, vacuum-insulated stainless steel construction as the classic tumbler, keeping your water cold and refreshing all day long. It also comes equipped with a wide-mouth design and twist-on, leak-proof chug cap complete with carrying loop; haul it around comfortably, or attach it to your backpack until you need it with a carabiner.
