When searching for matching bags for the Surface RT, I came across this double pack. Since red - black not individually is I had to order the kit. The bags were as always delivered quickly. The material offers front and back some protection against shocks. Laterally, the foamed material is pressed and only provides minimal impact protection. For me it was important that I have a protection against scratches and dirt for my Surface RT and also in the correct format. The Surface RT incl. Touch Cover Sleeve has yet minimal air aside and sits otherwise taut. The structure of the material is a matter of taste. It does not disturb me.
Basically, it would be 5 star, but a halo I deducted, since there were red and black only in a set with blue-green.
