I had been looking for such a linen bags for my Businessschläppchen when I always put in the trunk and also for home. For shoe size 41 the M bags fit perfectly. The size S is a little too small as it turned out. What is one to say a big linen bag as it seemingly well made and at an acceptable price. Ideal would of course if they were also approved by the manufacturer for washing. But also works that way. Short Hand wash with mild detergent and good.
