The Ultimate thinnest iPhone 17 Pro case for Everyday Carry

The Thinnest iPhone 17 Pro Case – Ultra-Slim or Ultra-Smart?

If you’re hunting for the thinnest iPhone 17 Pro case, you’ve probably seen options that promise near-naked feel and pocket-friendly profiles. But after testing a dozen of the slimmest offerings alongside something like the Smartish Gripmunk (and the ultra-slim Smartish Thin AF), I’ve learned a hard truth: the thinnest case is rarely the smartest carry. Here’s what actually works for daily use, travel, and drops.

What “Thinnest” Actually Means for Your iPhone 17 Pro

Ultra-slim cases typically measure between 0.35mm and 0.8mm thick. They add almost no bulk, but they also add almost no drop protection. Most rely on hard polycarbonate backs that shatter on impact or flexible TPU that yellows within weeks. For an EDC loadout where your phone is in and out of pockets, clipped to a belt, or tossed into a backpack, that tradeoff matters.

Best For: Everyday Pocket Carry Without Compromise

The Smartish Thin AF case hits the sweet spot: 1.2mm thickness (still invisible in jeans) with reinforced corners and a raised lip. It’s not the absolute thinnest, but it’s the thinnest that actually passes a 4-foot drop test without cracking. For comparison, paper-thin cases saved only 3g of weight but added zero confidence.

Tradeoffs You Need to Know

Ultra-slim cases under 0.8mm (Totallee, Peel, bare-bones knockoffs) – Pro: virtually invisible. Con: zero corner protection, slide off on hard floors, crack from a waist-high drop. For a $1,200 phone, that’s a gamble I won’t take in my daily carry.
Smartish Thin AF – Pro: real drop protection in a slim profile, MagSafe works, doesn’t yellow. Con: adds 1.2mm – still slimmer than a credit card, but you’ll notice it if you’ve been raw-dogging your phone.

How to Choose: Slimness vs. Real-World Protection

Ask yourself three questions:

• Do you work on hard surfaces? Concrete, tile, asphalt – then avoid any case without air-cushion corners.
• Do you use your phone one-handed? Ultra-thin cases are slippery. Micro-texture grip (like Smartish) helps without adding bulk.
• Do you carry a wallet? If yes, you probably don’t need a card slot on the case – keep it slim and use a separate minimalist wallet. The Thin AF supports MagSafe wallets cleanly.

EDC Verdict

For my own pocket – and for anyone who actually carries their phone through a workday, commute, and weekend – I can’t recommend sub-0.8mm cases. They’re fine for a desk phone that never moves. But for an everyday carry essential that takes bumps, drops, and pocket grit, the Smartish Thin AF is the smartest pick. It’s not the thinnest, but it’s the thinnest that won’t leave you holding a broken screen.

Need a case that disappears in your pocket but shows up when you drop it? That’s the one. Skip the hype, grab the grip, and carry with confidence.
