Anyone know where I can get a sup boardbag that doesn't come with a zipper that'll rust away within the year?

Bit annoyed about the top quality Balin cover that ive had for 12 months which now has only one working zipper.... my stuff gets a nice salt coating even in storage due to where i live.... 30 knot seabreezes straight off the ocean in into my shed all summer.

They make fine plastic zippers, work great on my ute canopy etc. I don't understand why they cant put them on board bags.

Just take your current cover to someone that makes canvas products had a zip replaced with large plastic one for $50 bucks good as new.
