Apple renamed the big-screen iPhone — \"Plus\" became \"Air\" — but the core question for anyone shopping a waterproof case hasn't changed: does the larger-format iPhone hold up in the rain, at the pool, or through a wet-hands fumble? We lined up the Waterproof Texture TPU Phone Case in its iPhone 17 Air fit against the same case family's iPhone 16 Plus fit to see how Red Pepper Cases' waterproof texture platform handles the size-comparable successor to the Plus line.
Core Philosophy Difference
Both cases come from the same waterproof texture TPU platform, which means the philosophy here isn't split by design approach — it's split by what each phone actually needs. The iPhone 17 Air is Apple's thinnest large-format iPhone yet, so its waterproof case has to protect a phone that was engineered to be as slim as possible without adding bulk that defeats the point of owning an \"Air\" model. The iPhone 16 Plus case, by contrast, is fitted to a slightly thicker, more traditionally-proportioned body, giving the case a bit more material to work with for the same waterproof seal.
iPhone 17 Air Waterproof Case: What It Delivers
The Waterproof Texture TPU Phone Case for iPhone 17 Air runs $53.91 and is precision-fitted to Apple's thinnest iPhone ever. That's a harder engineering problem than it sounds — a waterproof seal needs enough material thickness to actually seal against water intrusion, but the whole appeal of the Air is how little bulk it adds to your pocket. This case threads that needle with a non-toxic, odorless TPU compound that's more wear-resistant than ordinary plastic while staying thin enough to respect what makes the Air worth buying in the first place. The textured finish also solves a real problem specific to slim phones: thinner phones are easier to fumble, and a textured grip meaningfully reduces that risk compared to a slick, glossy case.
iPhone 16 Plus Waterproof Case: What It Delivers
The Waterproof Texture TPU Phone Case for iPhone 16 Plus runs $53.91 as well, built from the same wear-resistant, anti-yellowing TPU formula, precisely cut for the 16 Plus's larger, slightly thicker body. Because the 16 Plus has a more conventional profile than the ultra-slim Air, the case can prioritize a comfortable, secure grip without the same tightrope-walk between thinness and sealing integrity. If you're holding onto a 16 Plus and don't plan to upgrade before the next generation, this case gives you the same waterproof texture platform — and the same proven formula — fitted specifically to your phone.

Key Decision Factor
Since both cases share the same waterproof texture TPU platform and identical pricing, the deciding factor here is simply which phone you own — there's no meaningful protection or feature gap to weigh. What is worth noting is that the Air's case had a tighter engineering constraint to solve (thin phone, real waterproofing) and pulled it off without adding bulk, which is a reasonable proof point that this case family holds its formula together even under a harder design brief.
Context: Where Each One Wins
The iPhone 17 Air case wins specifically for anyone who bought the Air because they wanted the thinnest possible phone — it's the rare waterproof case that doesn't undo the reason you bought that model. The iPhone 16 Plus case wins for anyone happily running last generation's large-screen iPhone who doesn't want to compromise on proven, established waterproof protection just because a newer model exists.
What Both Cases Share
Both the iPhone 17 Air Waterproof Case and the iPhone 16 Plus Waterproof Case come from the exact same design DNA — non-toxic, odorless TPU material, wear resistance that outperforms standard plastic, anti-yellowing formulation, and precise cutouts for every port, button, and camera. Both are priced identically at $53.91, and both deliver the same waterproof texture protection philosophy, just tailored to two different phone bodies.
Customer Story
Tomas upgraded from an iPhone 16 Plus to an iPhone 17 Air this year and was nervous the waterproof case he'd loved on the Plus wouldn't translate to the thinner phone. "The whole reason I wanted the Air was how light it feels in my hand — I didn't want a case that made it feel like my old Plus again," he said. He was surprised the Air-specific waterproof case kept that slim feel while still surviving a genuine soaking during a surprise thunderstorm on a bike commute. "I got caught in a downpour with no warning, phone in my back pocket the whole ride. Pulled it out expecting the worst and it was completely dry inside." His partner, still on the 16 Plus, uses the same case family and says the fit and texture feel identical to what Tomas describes — just on a slightly chunkier phone.
