I have a pair of Schwalbe Active with the tan sidewalls and puncture protection. While not exactly a fast tyre they have been getting a lot of use. A combination of too much air pressure and a 700c tube forced the tyre off the rim after an hours ride when first fitted. Replaced the tube with a 27 x 1 1/4 and the with the pressure at 60 have had no issues. Pulled an industrial staple out of the tread a few weeks ago thinking it would puncture but so far so good.
