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! The Happy Trails NO-ZIP stroller also features an elevated paw rest. Your pet can easily look out of the stroller by using the front bar for support. The new panoramic view window allows your pet to remain safe inside of the stroller without missing any sights while you stroll! Interior dimensions: 24"L x 12"W x 22"H.
