So I searched for suitable protection and with this simple felt cover found. I went also about a low weight (it weighs only about 100g).
Attention! You have to pay attention to whether you want to use it for the Surface or Surface with Type Cover (the shell is quite accurately) when ordering.
But, boys and girls from WILDTECH: The shell is so expensive! ... But ok .... the you knew that beforehand and should not now lead to the devaluation ;-)
Conclusion: Simple but really good and really expensive ... anyway of me 5 stars
