HTC One M9 OtterBox-style cases

Designed to mitigate damage better than anything else out there, these cases for HTC One M9 are packed with layer upon layer of solid protection, inside and out. While some are bulkier than your standard skin case or hard case, they serve their purpose in absorbing impacts so your HTC One M9 doesn't have to.

There are a number of cases for HTC One M9 already available, but we've selected the ones that stand out and above the rest.

Caseformers Duo Armor Case & Holster

Adding a certain style, grip and security to your HTC One M9, the Caseformers Duo Armor case provides everything you need to steer clear of damage.

A textured silicone layer wraps around the M9 while the tough polycarbonate cover sits on top, featuring a grooved design that enhances grip and rocks a fold-out kickstand for watching movies. Included with the rugged case is a swivel clip holster that your HTC One M9 snaps into. Perfect for utility belts or clipping to your pocket.

Urban Armor Gear Composite Hybrid Case

If you're no stranger to sturdy cases, then you're probably familiar with Urban Armor Gear. Their composite hybrid case provides excellent impact protection in its own respect, while not overdoing it on size or extra layers.

This HTC One M9 case meets military drop-test standards and features one of the coolest designs that's paved the way for many others of its kind. Its tough plastic shell is fused with an impact resistant core that works hand in hand, shielding your M9 from serious impacts.

i-Blason Armorbox

i-Blason's Armorbox for the HTC One M9 provides the rugged looks as well as the protection. Featuring a built-in screen protector along with reinforced corners, this case is perfect for the accident-prone.

The inner TPU core of the Armorbox has a dotted pattern that i-Blason claims helps absorb impacts when they occur. The exterior shell, while similar in design to UAG's composite hybrid, is an extremely durable polycarbonate that features more than one texture for a comfortable grip. The edging also sports a cool tire tread design that gives the case a little extra edge.

Supcase Rugged Holster Case

Kicking it up a notch is Supcase's rugged holster case that holds the title for biggest beast of the bunch. The duo-layer hybrid back cover combined with a built-in screen protector and heavy duty holster make it a true contender with the OtterBox Defender.

The ports are temporarily covered to keep out dirt and debris when not in use and the included holster features a rock-solid clip that can be rotated 360-degrees for optimal comfort while at your side. Priced at only $9.95, though, we're skeptical how it may hold up in the long run.

Roocase Glacier Tough Hybrid Case

The Glacier hybrid case from Roocase administers rugged protection from impacts and scratches with a more transparent design on both the front and back.

The scratch resistant acrylic backing lets the original look of your HTC One M9 shine through while a thick TPU bumper wraps around the edges for superior impact control. A 5H screen protector is built into the front panel so you're safe from scratches at all times. Port plugs are also present on this case, which we can't argue with.
