YKK #10 Aluminum Complete Chap Zipper

The aluminum teeth glide through the slider with zero catching, even after I yanked them open and closed a dozen times on my workbench. I grabbed the 36-inch length for my chaps and the pull action feels solid as a truck door latch.

These replaced the zippers on my riding chaps and the aluminum teeth feel way sturdier than the plastic ones I had before. The 28 inch length was perfect for my pair, and the pull glides smooth even with thick leather.

Swapped out the old zipper on my leather chaps and this 36-inch one fit perfectly. The aluminum slider glides smooth and feels like it'll actually hold up to road grime.
