Ive used Incipio cases for the past year. Their silicrylic case on my blackberry 9850 was made with a soft plastic which felt awesome and was durable. I bought the feather for my iphone 5. Its not the exact same plastic they used on my old incipio case. Its the new "plextonium" and I like it. It has a soft and rubberized feel to it. Unlike most hard cases, it seems like this one can take a fall without a crack or chip. Feels really nice in my hands and still slides into my pocket easily.
Great light protection for iphone 5. The corners are covered and it has a side lip, but the lip is barely higher than the screen. Overall very happy and this will be my main case.
