Just curious because I have one with a zipper that needs repair.

May I take this opportunity to remind everyone that the empeg bags will get broken zippers if you try to insert/remove the player with the zipper only partially unzipped. The place where you've left the zipper "head" becomes a stress point and can wear out quickly. Always open your empeg bag fully, with the zippers unzipped all the way to the hilt, and you'll increase the lifespan of your empeg bag. My first empeg bag lost its zipper fairly quickly, but my second bag is still going strong now that I've gotten in the habit of unzipping it all the way.
