What Are the Slimmest iPhone Duo Cases?

Last updated October 31, 2026. The short list below is drawn from Amazon listings. We have not tested these cases, and the features quoted are the sellers' claims.

The iPhone Duo is chunky when folded, so a thin case is a popular ask. Sellers rarely publish thickness, though, and 'slim' on Amazon is a marketing word. The only hard numbers we found come from case-tester.com's scale: PITAKA's aramid case at 17 g and JETech's back shell at 30 g. Both are covered in our screen protector guide, and our thinnest and grippiest cases guide adds maker-stated thickness figures.

Short list: 8 listings to start with

We picked these from the 216 matching listings in our Amazon catalog to show a spread of brands and styles, favoring brands with more listings or reviewer coverage. They are listings, not tested picks, and they're in no particular order. The feature text is quoted from the seller's listing.

Before you buy

• Check that the listing names the iPhone Duo specifically. Some sellers list one case for several foldables.
• Look for mentions of a front frame and adhesive strips. WSJ and case-tester.com found both affect screen-protector use and how cleanly the case comes off.
• If you use a MagSafe car mount, check our MagSafe guide. Measured magnet strength varied from 0.88 kg to 1.84 kg in case-tester.com's test.
