UAG PLYO Case ($40)
Urban Armor Gear, or UAG, makes some truly durable and featherlight cases for Samsung's new Galaxy S9 and S9+.
What makes UAG cases popular is the extreme durability, reinforced corners with air-soft technology, an impact-resistant soft inner core, and the oversized tactile buttons that are easy to use. I hate cases with stuff buttons, as it makes phones hard to use and turn on. That's not the case with Urban Armor Gear stuff.
Each case from UAG is featherlight, using a slightly different style of TPU than most case manufacturers. It's durable yet flexible, so they're still easy to install. The company usually offers extremely industrial cases with fake screws on the back, which is a little too "manly" or rugged looking for some buyers. If so, try the new PLYO series. Anything from UAG will keep your phone safe.
