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.

Great! Works well with my Bob jogging stroller. Hilda so much stuff! The insulated pocket is really nice too.

I love how its made and will love it more when we can put it on the handle bar we didnt receive with our trailer/stroller.
