I bought this very last minute for a recent trip to Disneyland because the weather forecast predicted torrential rain. I was worried seeing the negative reviews, but there wasn’t a good alternative. Unfortunately, the forecast was correct. But this Bob Weather Shield was awesome! We had a full 11+ hour day at Disneyland/California Adventure and it poured 90% of the time. This rain shield was a lifesaver. It kept both our kids (4.5 and 1.5) dry and cozy, while the vents kept them from overheating. It was very easy to put the cover on the stroller first thing in the morning, and to lift it up for the kids to get in and out all day long. The bungee cords on the side worked really well. It fit our 2016/2017 Revolution Flex Duallie Double perfectly. I think it would fit all recent model years just as well.For reference, we also own a rain shield for our single City Mini GT stroller. It is a huge pain to get on and off—too much velcro that’s miserable to mess with in the rain. Plus the kids have always been too hot and stuffy in it.This Bob rain shield is the best!! 100% recommend.
