PrimaLoft®, the world leader in high-performance, sustainable insulation, introduces UltraPeak™, the new frontier of technical warmth and outdoor comfort.
The result of years of research, tradition, and innovation, PrimaLoft® UltraPeak™ redefines the standards of synthetic insulation: warmer, softer, and better performing than ever before.

Primaloft UltraPeak™

Revolutionary technology: warmth, volume and softness without compromise

Thanks to specially engineered fiber architecture, UltraPeak™ creates a unique structure capable of trapping body heat extremely efficiently.
The result is the warmest PrimaLoft insulation ever developed, with exceptional softness and long-lasting resilience.

The structure of the fibers generates a loft effect similar to down, offering a natural look and feel, but with all the advantages of synthetic material: light weight, quick drying and consistent performance even in humid conditions.

Sustainability and performance: the “Relentlessly Responsible™” philosophy

As is tradition with PrimaLoft, UltraPeak™ is designed with 100% recycled materials and produced with PrimaLoft® P.U.R.E.™ technology, which reduces CO₂ emissions by 50% or more compared to conventional manufacturing processes.
A concrete step forward toward more sustainable outdoor living, without sacrificing performance.

Primaloft UltraPeak™ a new standard for high-performance outdoor

The innovative structure of UltraPeak™ not only improves thermal efficiency, but also simplifies the processing of technical garments: the continuous roll material guarantees greater production efficiency compared to loose insulation.

A sustainable future for the entire PrimaLoft portfolio

With UltraPeak™, PrimaLoft continues its transition to low-emission production methods.
From 2025, the entire Gold Insulation range will be produced with P.U.R.E. technology, and future innovations will follow the same path right from the development stage.
