Why the iPhone 13 Pro Max Waterproof Metal Thin Case Is Essential for Swimmers and Everyday Minimalists
Most waterproof cases protect your phone by turning it into a brick. This one refuses. The iPhone 13 Pro Max Waterproof Metal Thin Case seals your 6.7-inch iPhone 13 Pro Max (2021) inside an IP68-certified shell of aluminum metal and silicone — submersible to 6.6 ft / 2 m for a full hour — while staying slim enough to slide into a jeans pocket without a fight. The clear back shows off your phone's finish and still passes wireless charging straight through. Built for swimmers, paddleboarders, beach parents, commuters caught in the rain, and minimalists who hate bulk, this is the best iPhone 13 Pro Max thin waterproof case for everyday carry. The Gorilla Family does not wait out the weather — and now your iPhone 13 Pro Max does not either.
Key Features
- 2 color choices: Black and Red aluminum frames, both paired with a crystal-clear back panel.
- Premium materials: high-quality aluminum metal frame, shock-absorbing silicone edge, clear polycarbonate back, and a built-in HD screen protector.
- Case type: slim full-body waterproof case with an upgraded snap-together design — easy to install and just as easy to take off.
- IP68 waterproof rating: certified submersible to 6.6 ft / 2 m underwater for up to 1 hour — pools, snorkeling, boats, rain, and sink accidents covered.
- 360-degree protection: shock-absorbing silicone corners make the case shockproof, dustproof, and sandproof for drops of 6 ft / 1.8 m.
- Slim profile: precise cutouts and a tight body keep the phone pocketable — no diving-bell bulk.
- Screen protection: built-in HD screen protector blocks scratches, dirt, and damage without hurting touch sensitivity or clarity.
- Camera protection: the sealed clear window covers the triple-camera array and stays optically sharp for underwater photos.
- Charging compatibility: the clear back does not block Qi wireless charging — charge without removing the case; note this is not a magnetic case and does not add MagSafe.
- Clear sound: acoustic membrane design keeps calls and music sounding clean with the case sealed.
- Compatibility: fits the iPhone 13 Pro Max (2021, 6.7-inch) ONLY. It does NOT fit the iPhone 13, iPhone 13 Pro, iPhone 13 Mini, iPhone 12 Pro Max, or iPhone 14 Pro Max.
Materials Explained — What Aluminum Metal and Silicone Actually Feel Like
The frame is genuine aluminum — the same material as camera bodies and high-end laptop shells. It feels cool, rigid, and reassuringly structural in the hand, giving the case its waterproof clamping strength without the weight of a full metal tank.
Running around the edge is a silicone anti-fall bumper, the same compound used in running shoe soles and swim goggles. It is grippy where your fingers land, and it compresses on impact so corner drops never transmit straight into the phone chassis. The clear back panel is hard polycarbonate — bike-helmet material — so your phone's color stays on display behind a scratch-resistant window, and the built-in HD screen protector up front feels nearly identical to bare glass under your thumb.
Altogether the case weighs about 2.5 oz (70 g) and adds roughly 2.5 mm of thickness — remarkably thin for a sealed IP68 case, which is the entire reason to choose this one.

Real-World Use Cases
- The Lap Swimmer: leaves the phone poolside through every splash zone and films underwater laps on weekends.
- The Paddleboarder: keeps the phone zipped in a board pocket knowing a capsize is an anecdote, not an insurance claim.
- The Commuter: walks ten rainy minutes to the train every day and never gives the weather a second thought.
- The Beach Parent: hands the phone over for sandcastle photos — sandproof sealing means grit stays out of the speakers.
- The Minimalist: wanted waterproof protection but refused to carry a brick; this is the compromise that is not one.

Step-by-Step Installation Guide
- Clean your iPhone 13 Pro Max with a microfiber cloth and confirm the phone and case interior are completely dry and lint-free.
- Unsnap the front and back halves, then lay your iPhone face-down into the front frame, lining up the camera window first.
- Snap the back panel on, pressing around the full perimeter until every clip clicks and the silicone seal sits flush.
- Inspect the edge line for gaps and make sure the charge-port plug is seated firmly.
- Test buttons, speakers, Face ID, and wireless charging — then run a 30-minute empty-case dunk test in the sink before the case ever guards your phone underwater.
Troubleshooting and Tips
- Touch feels slightly different after install? The built-in protector has a short break-in period — most users stop noticing it within a day or two.
- Wireless charging slow or intermittent? Center the phone on the pad; the sealed back adds a hair of distance, so alignment matters more than usual.
- Speaker sounds muffled after a swim? Water can sit in the acoustic membrane — shake it out and let it air-dry for a few minutes before judging the sound.
- Case hard to open? That is the seal doing its job; start from the designated corner notch and work around — never pry at the camera window.
- Cleaning the case? Rinse with fresh water after pool or ocean use and air dry. Never use alcohol wipes on the clear back or coated aluminum — they cause clouding and dull the finish.
FAQs
Which phones does this case fit?
It fits the iPhone 13 Pro Max (2021, 6.7-inch display) only. It does NOT fit the iPhone 13, iPhone 13 Pro, iPhone 13 Mini, iPhone 12 Pro Max, or iPhone 14 Pro Max — a waterproof seal only works with an exact dimensional match.
What comes in the box?
The two-piece snap-together waterproof case with built-in HD screen protector, plus a quick-start guide with sealing and testing instructions.
How deep and how long is it waterproof?
It is IP68 certified for full submersion to 6.6 ft / 2 m for up to 1 hour — ideal for swimming, snorkeling, boating, and rain. It is not intended for scuba depths or high-pressure water jets.
Does wireless charging work through the case?
Yes — the clear back panel passes Qi wireless charging without removing the case. This is not a MagSafe case, though: there is no magnet ring, so magnetic mounts and wallets will not snap on.
What is the drop protection rating?
The silicone shock-absorption corners and aluminum frame handle drops of 6 ft / 1.8 m onto hard surfaces while keeping the seal intact.
Does Face ID still work?
Yes — the sealed front window is optically clear over the TrueDepth array, so Face ID works normally with the case on.
Can I take photos underwater?
Yes. The camera window stays sharp underwater, and the built-in protector keeps the touchscreen usable at shallow depths — use the volume button as a shutter for the steadiest shots.
Are the buttons and ports accessible?
All buttons press cleanly through sealed covers, and the Lightning port sits behind a waterproof plug. Keep the plug closed any time water is nearby.
Do I need to add a screen protector?
No — an HD screen protector is built into the front half. Adding another protector underneath will break the waterproof seal.
Will the clear back yellow over time?
The back is hard polycarbonate rather than soft TPU, so it strongly resists the yellowing that cheap clear cases suffer. Rinse off sunscreen promptly to keep it crystal clear.
Is it slim enough for everyday carry?
Yes — that is the headline feature. At roughly 2.5 mm of added thickness and about 2.5 oz / 70 g, it is one of the thinnest sealed IP68 cases you can put on a 13 Pro Max.
Is it professional enough for work?
Absolutely — the Black frame with a clear back reads as sleek rather than rugged, so it will not look out of place in a meeting after a morning swim.
Is this a good gift?
It is a brilliant gift for swimmers, boaters, and anyone heading somewhere tropical. Free 30-day returns mean the fit is risk-free.
How do I know the seal is still good?
Run the 30-minute empty-case dunk test after any hard drop or every few months of heavy use. If you ever see moisture inside during the test, stop using it in water and contact our team.
What is the return policy?
Yes — Gorilla Cases offers free 30-day returns on all iPhone 13 Pro Max cases. If the case doesn't fit your iPhone 13 Pro Max or you're not satisfied, contact our team within 30 days for a fast replacement or full refund. No restocking fees.

What Gorilla Family Customers Are Saying
★★★★★
Thin enough to forget, sealed enough to swim
I swim laps four mornings a week and my Black case has been splashed, dunked, and once fully dropped in the deep end. Phone is perfect. The best part is it still fits in my jeans pocket — my old waterproof case did not.
— Elena V., Tampa, FL
★★★★★
Survived a capsized kayak
Flipped my kayak on the Coquitlam River with the phone in my PFD pocket. Twenty minutes of on-and-off submersion and not a drop inside. Wireless charging through the clear back still works flawlessly too.
— Graham L., Vancouver, BC, Canada
★★★★★
The Red one is gorgeous and tough
Bought the Red frame and the clear back shows off my Sierra Blue phone perfectly. It has survived beach sand, a rainstorm festival weekend, and my toddler's bath-time ambush. Touchscreen feels totally normal.
— Monica D., San Diego, CA
★★★★★
Perfect holiday gift for my wife
Got this for my wife before our Queensland reef trip. She filmed underwater video on day one and the footage came out crystal clear. Snap design was easy enough to install in the airport lounge.
— Oliver H., Melbourne, VIC, Australia
★★★★½
Excellent case, speaker needs a shake after swimming
Five stars for protection and slimness — it genuinely disappears in a pocket. Only quirk: after a swim the speaker sounds muffled until the water drains out of the membrane, which takes a few minutes. Small price for a dry phone.
— Caleb N., Portland, OR
