Leakproof. Sweatproof. Drop-proof. Adventure-proof. The rugged construction and vacuum insulation on this bottle means that it can handle anything—all while keeping your hot drinks hot and cold drinks cold for a full day. Slim enough for a one-handed hold, it’s even got a twist-and-pour stopper for smoother pouring. The insulated lid also doubles as a cup for drinking. Feel free to combine colors!
