The front two wheels of this Rolser Pack Tour Polar shopping trolley swivel meaning it is easily manoverable even in the tightest places. It is lightweight and has a stylish puffa style waterproof jacket. The team at Spring Chicken love the fact that you can quickly convert this shopping trolley from four wheels to two which makes it easier for you to move it around on different floor surfaces. Forget the old-fashioned shopping trolleys...Rolser is a cut above the rest!
