YKK | Cerniera a fine corsa aperta | Spirale in nylon | Blu navy | #5

The coil teeth glide smoothly past the separating slider every time, and the open-end design made attaching it to my duffel bag way easier than a closed-end would've been. Sewing it in took no time at all since the nylon is so pliable, and it holds up fine under the stress of a heavy load.

The #5 nylon coil teeth feel lighter than standard metal zippers, yet the pull action is smooth and sturdy. Worked perfectly for replacing the zipper on my daughter's backpack. Takes a bit of patience to sew through the coil, but the navy color matched my nylon fabric exactly.

I’d been hunting for this shade of navy for a jacket project, and the color is exactly what I needed. The coil zips up smoothly with no catching, though I wish the slider had a slightly bigger pull tab for easier grip. Overall, a solid workhorse zipper for the price.
