That is the exact model I use successfully on my Bob. It isn't a perfect fit (I undid the canopy Velcro and looped the footmuff elastic around the stroller back...hope that makes sense when you try it) but it works, and keeps my baby toasty in Milwaukee.

Also, I am able to collapse the stroller without removing the footmuff!

I never knew you could use something like that on the bob! I just put my kids in a bunting and then use a cotton or fleecey blanket tucked around their bottom half. I've taken them out into the 30s without any trouble that way.
