I purchased the wind/rain guard at the same time I purchased my BOB Duallie Jogger. I am so glad I did. The individual canopies on the stroller are great, don't get me wrong. They are very versatile. However, on those especially windy days, or on those days when a surprise summer shower pops up, it has been a life safer to pull out the wind guard and slip it on and keep going. It is well constructed with quality material. I have had this cover for almost three years actively using it, and still no rips/tears and the plastic has not fogged. The cover fits the stroller well and allows for ventilation. The girls think it is fun when we put it on, kind of like a princess tent on wheels, kid imaginations will never cease! The wind/rain guard fold/compacts easily for storage in a pocket of the stroller so it is always handy. If you are planning on using your stroller often, I highly recommend this accessory.
