OnePlus 5 Silicone Case ($20)
Next is the official OnePlus silicone cover. It comes in two colors, black or red, and offers a soft finish that many will enjoy.
OnePlus is using three layers of medical-grade Silicone that are precision molded to perfectly hug your OnePlus 5 phone. Silicone is soft and easy to install, extremely resistant to forces from drops, and won't scratch or fade over time.
We were going to recommend this extremely rugged holster and kickstand case, but it won't be available for over a month.
Instead, get something thin, lightweight yet very durable and drop-resistant, which is the Silicone case from OnePlus themselves. You won't be disappointed and it's only $20.
