NANGA × YKK's Anti-Snagging Zipper Construction
Our sleeping bags are equipped with specialized YKK parts on zipper sliders to minimize snagging and catching of the fabric

When using a sleeping bag, there is a risk of the zipper catching on the super-thin fabric and preventing the opening and closure of the bag. If severely snagged, the zipper may even cause damage to the fabric. To mitigate such problems, we have attached special YKK parts to the zipper sliders. These parts are developed to diminish the gaps in the zipper slider that causes the snagging, resulting in fewer occurrences of the fabric getting caught as well as reduced damage to the fabric in case of such events. Furthermore, the parts are made from lightweight resin (weighing 1.6 g per piece) with phosphorescent features for easier operation in the dark.

The concave structure at the top of this specialized slider component pulls in the fabric towards the center to prevent the zipper from snagging.

The phosphorescent material glows in the dark to make the zippers easier to handle.
