I really can't fault it. It is a perfect fit for my Schilke 59 MP, and the zipper action is nice and smooth.
I like the Neoprene material too, nice and spongy to absorb any bumps or dropsies.
Since this is also designed for Clarinet/Saxophone MP's, it also has a small external pocket for reeds. Not sure what I can use that pocket for just yet!
