There is the silicone cover that you can buy and the padded fabric type, which i don't recommend. I bought the fabric one for my H5 and only used it one trip. It was very tight to get on/off and the power button would get pressed and it drained the battery over night before a day out. I didn't know until i got to the lake. I might try the silicone one for my H7 but haven't wanted to spend the dollars yet.
I bought a Rapala hand cloth from Cabelas a few years ago. I noticed if it is folded in half and the side sewn it would make a perfect H7 cover to keep dust and crap off when not it use. I think any normal micro fiber cloth would also work. Not really the case answer you're looking for but maybe an option.
