At its core is innovative, body-mapped Mammut LOOPINSULATION—a sustainable synthetic fill made from industrial rope offcuts blended with recycled plastic. Zoned insulation delivers dependable warmth where you need it most while reducing bulk in high-movement areas. The ultra-light face fabric is soft against the skin yet wind- and abrasion-resistant, finished with a PFC-free DWR to shed light moisture.

Thoughtful alpine details—including an adjustable hood, backpack-compatible pockets, and a two-way front zipper—make the Rime IN an adaptable outer layer or a reliable midlayer under a shell. Designed for longevity, it’s also engineered for easy repair, ensuring seasons of dependable performance.
