What Is Tech21 and Who Is It For?
Tech21 presents itself as more than a case maker. According to its UK website, an in-house team of scientists works on patented materials designed for impact protection, and the company says those materials protect millions of mobile phones. Its range includes the EvoClear line, eco-friendly cases made with recycled materials and bio-technology formulas, and some products with antimicrobial protection.
Tech21 is a strong fit for:

Tech21 Review: Key Features
What Makes Tech21’s Materials Different?
Tech21’s main selling point is its focus on materials. The company says its in-house scientists develop patented impact protection materials rather than relying on generic plastics. We could not confirm lab results from the pages we read, so we treat this as a company claim, but it is a clear statement of where the brand puts its effort.
Does the Tech21 EvoClear Range Turn Yellow?
Tech21 says it does not. According to its UK website, the EvoClear range uses a UV-resistant formula that the company says stops yellowing for the lifetime of the device. Yellowing is one of the most common complaints about clear cases, so this is a useful feature if you want to show off your phone’s colour.
Are Tech21 Cases Eco-Friendly?
Tech21 sells an eco-friendly range made with recycled materials and bio-technology formulas, and it claims multi-drop protection for its biodegradable range. That means you do not have to give up the brand’s protection focus to choose a lower-impact case. Check each product page for the exact materials used.
Do Tech21 Cases Have Antimicrobial Protection?
Some do. Tech21 offers antimicrobial protection on some products, but not on every case, so look for it in the product description before you buy if it matters to you.
Are Tech21 Cases MagSafe Compatible?
MagSafe compatibility was not stated on the pages we read. If you use magnetic chargers or accessories, check the individual product page on the brand’s website before ordering.
