Had me by eye first concerned a stand bag from Hama. Had times before 'nen eye test should make the optician. Because the length was reasonably ok, only the diameter not. After that, even with some risk, this Stativtasche ordered in size M. I was not sure if M is sufficient. Fits but perfect. Top is not a lot of air, but the tripod should not wobble from side to side as well. Quality a lot better than the Hama Bag what mglw itself. explained by the difference in price.
