I used to live in a city where 90% of the year - it's raining. Even though I have the hard case, my cello, with winds and hard rains, would get wet, so I found this cello rain coat which solved my problems. It comes in a small and handy package, where you can store it for carrying in your bag/backpack. The coat itself is practical; you put it on from top to bottom, and then at the back side, there is a strap that you connect for securing. Works perfect for my hard case, as well as for the soft one. The material is great, and it dries within 10-15 minutes afterwards. Totally recommending it!
