Thinborne vs. Latercase Galaxy S25 Ultra Case: In-Depth Feature & Pricing Comparison in 2025

If you're after a case that preserves the sleek profile of your Galaxy S25 Ultra, both Thinborne and Latercase offer minimalist designs.

Thinborne’s S25 Ultra case is built for real-world use. Made from aerospace-grade aramid fiber, it adds modern protection without bulk. The Latercase S25 Ultra case, created by Lew from Unbox Therapy, leans toward sleek aesthetics and a durable matte finish.

Both brands deliver unique takes on modern protection and minimalist design, but they have their own sets of differences. In this blog, we will go behind each case and see how they shape your daily experience with the Galaxy S25 Ultra.

Thinborne and Latercase are two businesses that aim for minimalism with different takes on how to achieve it. When you're aiming to protect the Galaxy S25 Ultra without bulking it up, they both offer ultra-slim solutions.

The Latercase S25 Ultra case is made with aramid fibers and a minimalist design language. It preserves the S25 Ultra’s original shape and feel with as little interference as possible.

Thinborne, meanwhile, approaches minimalism with utility in mind. Crafted from aerospace-grade 600D aramid fiber, their S25 Ultra case adds a bit more grit. Literally. The textured surface enhances grip, while the design keeps a slim profile that won’t snag in your pocket. It’s a quiet performer, made to look subtle but act tough.

Here’s a side-by-side on their respective features:

Now, let’s dig into how these two materials and builds hold up in everyday use.

Aramid fiber applications are unique in their own right. While both Thinborne and Latercase use this high-performance material, their execution tells two very different stories.

The Latercase S25 Ultra case uses an aramid fiber focused on aesthetics. It’s ultra-thin, soft to the touch, and keeps your phone looking original.

Thinborne, on the other hand, steps up with 600D aramid fiber. The result? Better rigidity, longer wear, and a carbon-fiber-style texture that improves grip without sacrificing thinness. It’s engineered not just to look good, but to last longer and handle the everyday better. It highlights why aramid fiber should be chosen in a Galaxy phone case.

When you’re shopping ultra-thin, millimeters matter.

The Latercase S25 Ultra case measures just 0.6mm thin, making it feel almost non-existent. Ideal for minimalists, yes, but that thinness can offer very little in the way of impact protection.

Thinborne uses the space on their case wisely: a reinforced frame, grippy carbon texture, and enough structure to resist minor drops. It still slips easily into your pocket, but offers a confidence boost in day-to-day activities.

MagSafe isn’t just for iPhones anymore. Its expansion has become a reason why you should get a MagSafe case for your phone. With magnetic accessories expanding across Android platforms, Galaxy S25 Ultra users are now looking for reliable magnetic-ready cases.

Thinborne comes MagSafe-ready out of the box, with powerful internal magnets that are precision-aligned for mounts, wallets, and battery packs. No extra hardware needed.

The Latercase S25 Ultra case offers a MagLock add-on, which means magnets aren’t built into the case by default. It supports basic functions like charging and other magnetic attachments.

If magnetic convenience is part of your day-to-day setup, Thinborne offers a more seamless and secure experience.

Here’s where things really separate, what’s included, and what support you can expect:

If you’re after the lightest case possible and care mostly about preserving your phone’s natural feel, Latercase might suit you. But if you want added grip, stronger MagSafe, better protection, and value-packed extras, Thinborne is the more complete package.

Here are authentic reviews from our very satisfied customers:

“If you're looking for a super thin, yet durable and non-slip case, this is definitely one to consider. The fit is perfect, and I like that it doesn't have a big lip around the edges, since that really allows for a more natural swipe experience since you're finger isn't butting up against the case and missing the edge of the screen. The box includes a screen preparation kit and screen protector to provide added protection without much added bulk. As others have mentioned, the packaging is premium, as is the case itself. Be aware, this isn't a heavy duty protective case, so if that is what you are looking for then you should consider other alternatives, but if you're looking for thin, then this is certainly one to consider.”

“Very pleased with this case as the cutouts are precise and the feel is as if there is no case there but the build while light weight is very durable and protective! Extremely easy installation. And with the sleek cutout around the volume toggles and button area allows for literally real feel touch eliminating the snap or rough operation of the buttons with most other cases I've had over the years. The black 'fiber' construction of the actual case is absolutely beautiful. While other cases have presented some sort of flaw, whether it be feel, bulkiness, or alignment issues, you won't experience any of that with this one and I highly recommend!”

In the end, both Thinborne and Latercase Galaxy S25 Ultra case offer ultra-thin protection for the Galaxy S25 Ultra, but they serve different priorities. Latercase keeps things light and design-focused, ideal for those who want minimal bulk and a clean look.

Thinborne, on the other hand, delivers added grip, stronger MagSafe support, and more durable materials, making it the better choice if you want slimness without sacrificing everyday performance.
