| Benefit | Durability without much weight gain |
| Used in | Insulated jackets, lightweight shells |
Pertex Diamond Fuse is a lightweight fabric engineered for dramatically improved tear and abrasion resistance, using high-tenacity yarns in a fine diamond-shaped ripstop grid. It lets insulated jackets and shells stay light and soft while resisting the snags, scuffs, and tears that plague delicate ultralight fabrics, extending durability without much added weight.
Durable yet light

Frequently asked questions
What is Pertex Diamond Fuse?
Pertex Diamond Fuse is a lightweight technical fabric designed to be much more tear- and abrasion-resistant than typical fabrics of similar weight. It achieves this by weaving high-tenacity yarns into a fine, diamond-shaped ripstop pattern, so the fabric resists snags and scuffs while staying light and soft.
How does Diamond Fuse improve durability?
The diamond grid of strong yarns distributes and arrests forces that would otherwise tear or abrade the fabric, so small damage doesn't spread and the surface holds up to repeated rubbing. Pertex reports large gains in tear and abrasion resistance versus standard fabrics of comparable weight.
Where is Pertex Diamond Fuse used?
It's used where designers want lightweight gear that survives real-world abuse — insulated jackets, active shells, and pieces that face snagging on rock, brush, or pack straps. It lets brands keep weight low without the fragility that often comes with ultralight fabrics.
