Caseology is another brand I've been using more and more lately. In fact, it's what I used on the LG G5 and Galaxy S7 Edge for most of 2016. This brand has a good selection, starting out with two excellent LG G6 cases as of right now.
The Caseology Parallax is our recommendation. It has a subtle texture to the back for ease of grip and extra drop protection. It's made with a matte black TPU material. One aspect I like about all of their cases is the two-tone color and material. The outer edge has a space gray color in a hard polycarbonate plastic. Adding a premium feel without the bulk, thanks to the rest being TPU. It looks good and will get the job done in terms of protection.
