It reminds me of the Apple silicone cases, plus texture from the colored bits. A little powdery, but the last time I had an Apple silicone case, I recall that the “powdery” wore off, like it does on an Apple watch band. I got an elderberry silicone case for my 14 Pro, but haven’t used it yet. They feel very similar to me. but for the textured bits on the Otterbox. Personally, I like the feel.
FWIW, on my screens at least, the color rendering seems more accurate on the Otterbox site than the Apple site, where this seemed closer to white than gray (to my eyes).
