I have the 6 in an Apple silicone case. Love this combination but sometimes want something to carry it on (don't often have pockets and no screen protector for me this time). I've struggled to find a nice leather sleeve which will fit the phone in a case in. I've tried several from Etsy but mostly they look cheap and nasty. Nothing is as soft as the Sena leather. Anyhow my query is: Any idea if Sena cases for the 6 plus or other smartphone models will fit the 6 in an Apple silicone case. Has anyone tried this?
