InsulatedSingle Universal Stroller Organizer by Booyah Medium Pet.

I tried multiple organizers with my two kiddos and this one is superior by far - I have this one and the one for double strollers. The insulated cooler is top notch. So much storage.

very nice organizer well made. But I had to return it because I already had one I forgot about.

This attached to our stroller for our small 4 lb. toy poodle. The handlebar bag fits our stroller and has 4 different pockets to store items for the dog and also for our needs while we walk her. The pockets are all roomy and the middle pocket has a zipper to enclose securely items and cover them if it rains. Works well and highly recommended.

This product was part of the suggested together at the bottom of the Booyah Large Pet Stroller/Trailer but it doesnt fit. The handle measurements are just over 21 on the inside. Around 24 measuring on the outside. There are maybe 6 inches where this doesnt met the other side. Im sure this product would work just fine on the right size stroller (the medium or smaller). Not sure why this one was paired with the Booyah Large Stroller (I included a picture). Nevertheless, seems like a good product. Looking forward to getting one a bit bigger. Lesson learned: do some extra measuring even if the product is suggested with another item. PS. Amazon was very nice about it and helped me with a refund and I suggested putting a larger organizer with the stroller/trailer I purchased. All is well. I originally didnt put a rating because I didnt get to use it. Does seem well made though. Plenty of pockets. 6 velcro straps for stay-put-ability. The price was good. Id give 5 stars for all of these reasons and if it was comfortable to use while run/walking (so I put 5 stars). I would say that if your strollers handle bar is around the 19 - 20 wide measuring outside, then youre probably good.
