I went on apple.com and was thinking of getting a Tech21 case as I like how it's grippy for my 6s+ but the case won't be available until mid-November, after Nov 3rd. I also considered Otter, but they are also not available on Nov 3rd. I thought Apple's silicone case to be too hard rubber like, and not grippy. Any ideas on cases that are grippy that I can buy on Nov 3rd or before? And where I could get it? Thanks!
