Spigen Thin Fit
Aside from genuine leather cases my all-time favorite latest has been the Spigen Thin-Fit. As the name implies this is a case from Spigen that we all know, love and trust, only extremely thin and form-fitting for the least amount of added bulk.
Basically, this will keep the phone safe while keeping it as thin and lightweight as possible. The only downside some see with it, is the "snap-on" design. As a result the top isn't 100% covered by the case. That said, the corners or screen are what hit the ground when dropped, so this shouldn't be a concern.
The company uses a form-fitting process made out of a durable polycarbonate plastic, and finish it with a soft-touch non slip matte finish. It's one of the best LG G6 cases around, and it's only $12.99
