Jack Wolfskin Thermo Bottle

A rubberised coating provides a more secure grip than most others. Better still the insulating properties are good. You get a press-button closure plus a cup. But others offer better insulating performance for their weight and not everyone is a fan of button-operated pourers, as they tend to clog.
