If your garment has zippers, the sliders, pulls or the entire zippers can be replaced with a lockable version.

Lockable pulls

Works if you have two sliders.

Sliders with hasps

Also two sliders are needed. Hasp sliders/zippers are the easiest to find and the most secure/reliable solution. Such zippers are used in, for example, backpacks and bags.

Key lock sliders

The most invisible and discreet way.

I could not find the lockable slider on Opti site.

See what’s available on eBay.
