Graco Sporty

Bought it entirely because it said you can fit four bottles in the insulated pocket. I can just about squeeze four full-sized Dr Browns in there with tops but it's challenging, four with travel lids fit very easily if you put the tops in the other side.
It certainly won't win any awards for looks but personally I don't care about that. It's very big and has got a good selection of pockets. My only complaint is that the detachable waterproof bag sits over one of the internal mesh pockets making that mesh pocket pretty inaccessible, I'm managing fine without it though.
All in all it's a very practicle bag, particularly if you're bottle feeding and need to carry several feeds with you. It's also cheap compared to a lot of other bags out there.
