Speck Presidio UltraImage by SpeckSpeck has many variations on its Presidio case, and the most rugged is the $49.95 \nPresidio Ultra, a two-layered rubbery case sandwiched inside a two-layered hard polycarbonate bumper for four layers of protection. It even covers the buttons and ports to keep out dirt. Speck says it can survive drops of 15 feet.Speck Presidio Grip + GlitterImage by SpeckThe \nPresidio Grip + Glitter has grippy panels to help you not drop it, as well as a shock barrier inside for 10-foot drop protection. It's a little less fussy than the Presidio Ultra, too, with an all-in-one design and open ports. You can get the plain \nPresidio Grip for $39.95 without embedded metallic glitter, but to be honest I prefer this sparkly version for $44.95.Caudabe SynthesisCaudabe thinks serious protection shouldn't need to add a lot of extra bulk, and the $29.95 \nSynthesis is a slim case that consists of a hard back and an attached flexible bumper that absorbs bumps and shocks. The company says it can survive a drop of 3 meters (just under 10 feet).OtterBox Pursuit SeriesImage by \nOtterboxOtterBox\u2019s iPhone X cases all leave the screen uncovered, since it has that slight curve at the edges, but the rubber-and-polycarbonate \nPursuit ($69.95) is the most protective, while still staying slim. The two-piece case seals up the phone to keep out dirt and dust. It\u2019s slimmer than the $49.95\u00a0\nDefender, but you\u2019ll want to go with the Defender if you need a belt clip.OtterBox Statement SeriesImage by OtterboxIf you\u2019d prefer a one-piece design, the $39.95 \nOtterBox Statement Series for iPhone X has a leather panel on the back, along with a clear pane that lets your iPhone\u2019s design show through. It\u2019s also slimmer than OtterBox\u2019s two-piece cases, while still boasting the company\u2019s \u201ccertified drop protection.\u201dLifeProof SlamImage by LifeProofDesigned to withstand 2-meter drops, the $49.99 \nLifeProof Slam has a transparent back to show off that Apple logo. If you want the ports covered to keep out rain, snow, and dirt, you can step up to the $79.99\u00a0\nNext\u00a0(not shown here).LifeProof FreImage by LifeProofLifeProof also offers a fully submersible iPhone X case, so you can take it underwater and try Portrait Mode on whatever sea creatures you find. The \nLifeProof Fr\u0113 can survive in 2 meters of water for 1 hour. Surprisingly slim, it still fully covers the screen, speakers, mic, and all ports.\u00a0Urban Armor Gear Plyo SeriesImage by Urban Armor GearThe $39.95\u00a0\nPlyo has a one-piece design so it\u2019s easy to put on, but it\u2019s got a hard outer layer and a softer inner layer, including plenty of protection for your iPhone X\u2019s corners. Urban Armor Gear has more rugged \niPhone X cases like the $59.95 \nMonarch with leather trim and the $39.95 \nPlasma, but we like the understated looks of the Plyo\u2014and all the cases meet military drop-test standards.Nomad Rugged LeatherImage by NomadBoasting 10-foot drop protection, the $44.95 \nRugged Leather case from Nomad is the rare rugged case that will actually get better looking the more you use it, as the leather\u2019s patina develops. Inside is a hard polycarbonate layer, and a rubber bumper around the edge to protect the bezel and corners. Even though all that, wireless charging still works.Griffin Survivor Fit and Survivor StrongImage by Griffin TechnologyGriffin\u2019s \nSurvivor line of cases for the iPhone X starts with the $29.99 Survivor Fit (left) and its sibling the $29.99 Survivor Strong (right), but we prefer the Fit\u2019s textured back, which adds a little grippiness. Both are nice and slim but still rated to withstand drops of 7 feet. The Survivor Strong even comes in clear.Griffin Survivor All-Terrain and Survivor ExtremeImage by Griffin TechnologyGriffin has two iPhone X cases rated for drops of 10 feet. The two-piece $49.99 \nSurvivor\u00a0All-Terrain (shown on the left) completely covers the iPhone X, including a built-in screen shield and a see-through back. The three-piece $49.99 \nSurvivor Extreme (right) is just as protective, also has a plastic screen shield, and comes in two colors.Incipio Reprieve SportImage by IncipioThe $39.99 \nReprieve Sport is drop-tested to 12 feet, and has reinforced corners to absorb shocks. The back is clear polycarbonate to show off the Apple logo, and we like how it doesn\u2019t cover the Mute switch, which can be tricky to use through a case.Incipio DualProImage by IncipioIf you prefer a pop of color with your iPhone case, Incipio\u2019s $29.99 \nDualPro offers the same 12-foot drop rating as the Reprieve Sport, but comes in 9 bright color combinations. There\u2019s even a rose gold option for anyone who\u2019s sad the iPhone X only comes in black or white.Casetify ImpactImage by CasetifyFor protection with flair, Casetify's \nImpact line of cases comes in dozens of artistic patterns, like \nthis gorgeous lemon tree motif. The corners are reinforced with shockproof material, and a raised bezel should keep your screen from hitting the ground, and you can even choose the color of the bumper. If you want the Impact case \nwithout the fancy design, that's available too.
