Why the Galaxy S25 Ultra Carbon Fiber Case Matters in 2026

Customer Story: The Medical Device Engineer
Tristan Okafor, a 37-year-old medical device engineer from Minneapolis, Minnesota, carries his Galaxy S25 Ultra to laboratory environments, hospital client visits, and industry conferences.

After three different cases that either yellowed, cracked, or blocked the S Pen slot incorrectly, he discovered the Gorilla Cases Galaxy S25 Ultra Carbon Fiber Case through a Gorilla Family recommendation online.
Eight months later, the case looks exactly as it did on day one — no yellowing, no cracking, no lint accumulation in the weave thanks to the anti-static coating. The S Pen slides in and out perfectly. Tristan used code 10OFF and says the Gorilla Cases carbon fiber case is the last Galaxy S25 Ultra case he will ever need.
Protection Tips from Gorilla Gearheads
- Clean weave monthly with soft brush: Use a soft toothbrush and compressed air monthly to clear dust from the 3K carbon fiber weave between thread bundles.
- Avoid petroleum-based cleaners: The structural resin coating is degraded by petroleum solvents. Use 70% isopropyl alcohol on a microfiber cloth only.
- S Pen ejection: press firmly and squarely: The 0.1mm tolerance is tight — always press the ejection button straight on rather than at an angle to prevent S Pen tip from catching the edge of the carbon fiber case.
- Add tempered glass for full protection: Carbon fiber protects the back and sides of the Galaxy S25 Ultra — pair with a Gorilla Cases tempered glass screen protector for complete protection.
- Store away from metal tools: Sharp metal tools can scratch the resin coating. Use a dedicated pocket to prevent surface damage from keys and coins.
- Check corner bumpers annually: Inspect the TPU corner bumpers yearly for compression set or cracking, especially if the device has been dropped. Replace the case if bumpers have deformed significantly.
- Pair with S Pen tip replacement kit: Frequent S Pen users should replace S Pen tips every 6 months. The carbon fiber case edge can cause slight S Pen tip wear on extended use — a fresh tip ensures precise writing.
