Incipio Octane Texture Case ($12)
Incipio is another trusted name in smartphone accessories, and one of the most popular iPhone case manufacturers. In fact, carriers like T-Mobile, Verizon, and AT&T carry all of their cases in select retail stores.
The Incipio Octane looks to be one of the best cases for the HTC U11. It features a dual layer soft and hard shell design, added texture for a good grip, and tons of durability. It could be the most durable case available as of right now.
You'll enjoy a soft and textured TPU bumper on the entire outside of the case. This makes it easier to hold and grip and prevents damage from drops. However, the rest of the case and on the back is all a hard shell polycarbonate plastic. So it's extremely durable, while still being easy to install and use daily.
The Incipio Octane for the U11 comes in three colors and runs $24.99
