What kind of component is the stay-down puller mentioned in the windbreaker description?
After seeing the unfamiliar component name written in the windbreaker's detailed description, the shopper is curious about how it differs from a regular zipper.
A stay-down puller is a component where laying the pull-tab down engages a locking mechanism, helping prevent it from dangling or unzipping while running.
Stay-down means locking the pull-tab in place by laying it down. With regular zippers, the pull-tab easily bounces and dangles when moving vigorously. In contrast, with this puller, pressing the pull-tab down engages an internal latch so it does not shake out of position.
SAN SAN GEAR applied a stay-down puller to the BREEZE WIND BREAKER to prevent the zipper from dangling while running[1]. Because the pull-tab does not tap against the collarbone area or make metallic clinking sounds while running, you can fully focus on the movement of running. In addition, considering scenarios where a running vest is layered over it, it was designed with a slim fit that narrows the garment's width[2].
hmmm, from the latch of a small component to the garment's width, it is a build with standards set on reducing irritations for the runner.

The specific manufacturer of the zipper used in the BREEZE WIND BREAKER or detailed windproof specifications of the fabric have not yet been confirmed.
