Meet the One Big Unit
The My Mate Dug 2L insulated water bottle brings big-capacity hydration to workdays, gym sessions, road trips and camping adventures. With room for two litres, it is made for days when a little bottle just won't cut it.
Double-wall stainless steel provides insulation, while the wide mouth makes filling, adding ice and cleaning easier. A powder-coated finish adds a bold splash of colour.
Your bottle. Your choice of lid.
Your choice of lid is included with every One Big Unit. Options include a Flip Top Lid, Sippa Straw Lid and Carry Handle Lid (standard screw top).
The Carry Handle Lid and standard screw-top lid are the same lid: a screw-top design with a built-in carry handle.
The 2L and 1.1L bottle lids are interchangeable. When choosing a straw lid, select the option labelled for the 2L bottle. The dedicated 4L lid is not compatible.
