I use this bag for nature photography in snow. It's a great bag but be sure you get the right size for your camera. My first choice was backordered and not available (for months) so I was forced to purchase a bag that was a bit bigger. The bag does what it says it will do and keeps snow and cold out but if the bag is baggy it swims around the camera. It is an outstanding design however it takes some learning curve getting used to it. [...]You have to get used to "Feeling" every dial on your camera since you can't really see where your hands are inside the cool sleeves. If you've got the time to work with it, I highly recommend it for camera protection if you are in heavy snow conditions or extreme cold (below 0 degrees).
