The linen has a spring-like, in my opinion, very nice, color and rubbed off from the first wash not (significantly). I was in front and see no difference in color after the first wash between. The sheets must not be ironed, which I think is beneficial.
The material is in relief and feels comfortable on the skin. The structure he also does not stick if in warm weather you should sweat at night times.
The zippers work well and are a bit hidden under the fabric, so that they do not interfere.
