Pet Gear's NO-ZIP Expedition Pet Stroller has many new, exciting features. Our largest stroller offers a spacious, comfortable ride for both single and multiple pets. It features two easy-locking doors. Pets can now be loaded from either the front or back of the stroller and exit without having to turn around- a huge benefit for large or injured pets. No zippers means no hassle when trying to open and close the stroller. Our new NO-ZIP technology means that you can easily gain access to your pet without fumbling with difficult zippers! We've also added a multi-position handle which means more comfort for you while pushing the stroller.
