ThinBorne vs. Simply Carbon Fiber Case for iPhone 17 Pro Max (Features, Pricing, & Perks)

Simply Carbon Fiber is a provider of premium, high-tech accessories for enthusiasts of quality and modern engineering. It is focused on using authentic materials like genuine carbon fiber and aramid fiber, which offer a distinct, high-tech look and feel that is strong yet lightweight.

Beyond phone cases, the brand offers a variety of personal and home accessories, including wallets, key organizers, and license plate frames, all made with carbon fiber.

This brand does not seem to have the same level of awareness or marketing budget as competitors like Pitaka or Latercase, so we can relate to it in a way.

In this guide, we’ll look at two iPhone 17 Pro Max carbon fiber case options: Thinborne and the Simply Carbon Fiber case for iPhone 17 Pro Max. Both offer lightweight protection and minimalist designs and position themselves as a lifestyle brand.

Thinborne has one ultimate goal since the beginning: to protect your iPhone without adding bulk. Meanwhile, the Simply Carbon Fiber Case has a mission to bring the feel and prestige of “authentic carbon fiber” into everyday products.

We’ll look closely at their features below.

Thinborne uses authentic 600D aramid fiber, a material known for its strength, flexibility, and durability.

The 600D weave is tighter and more refined than 1500D, giving Thinborne a smooth finish and ultra-thin profile. The result is a case that is resistant to bending and cracking.

The Simply Carbon Fiber Case for iPhone 17 Pro Max, on the other hand, shows conflicting material information on its product page. In one area, the case is described as being made from real aramid fiber, while elsewhere on the same page, it claims to use real carbon fiber and forged carbon fiber.

These materials perform very differently, so the inconsistency makes it difficult to know what type of material you’re actually getting, which is very important. Carbon fiber is more rigid and prone to cracking, while aramid fiber offers better flexibility and impact resistance.

Thinborne integrates MagSafe and Qi wireless charging support through a magnetic ring that’s embedded within the case’s structure. This ensures consistent alignment and dependable hold with MagSafe accessories.

The Simply Carbon Fiber Case for iPhone 17 Pro Max also supports wireless charging, but doesn’t emphasize its magnetic strength. Also, depending on the material used, its magnetic compatibility may vary. If the case uses carbon fiber components, this material can interfere with magnets.

Look, this X user loves his Thinborne MagSafe case:

Thinborne provides everyday protection thanks to its impact-resistant aramid fiber. It can protect your iPhone 17 Pro Max from scratches and low-impact drops. Oh, and you’ll also get a free tempered glass for added protection.

Simply Carbon Fiber also comes with protective properties. For one, it has a raised front edge to safeguard your screen. However, if the case is made from carbon fiber, it can be brittle, making it prone to cracking. Of course, if they’re using aramid fiber, the degree of protection improves.

However, due to their inconsistent descriptions on their product page, the durability of their phone case remains uncertain.

Thinborne features a refined 600D weave with smooth texture that enhances grip. The case also features precise cutouts for the buttons and ports. Its uniform finish also adds to its premium minimalist design.

Simply Carbon Fiber, as its name suggests, is known for its carbon-fiber look. If the case is made from carbon fiber, it gives a unique look and a rigid feel. So, for craftsmanship, this will depend on the material used (which is quite confusing given the brand’s inconsistent listing).

Take a look at Thinborne’s new red edition iPhone 17 Pro Max Case:

The Thinborne iPhone 17 Pro Max case is priced at $69.69, which reflects its use of premium aramid fiber and MagSafe compatibility. It’s a high-quality, ultra-thin, yet protective option.

As for the Simply Carbon Fiber case for iPhone 17 Pro Max, its official site shows that it’s priced at $39.99, down from its regular price of $64.99. This lower price makes it a good value pick - although, as previously discussed, its material clarity is not as transparent as Thinborne’s.
