With new UltraPeak, Primaloft says it has developed its warmest insulation to-date.
Within its structure, unique architectural fibres intermingle with surrounding microfibres to create a scaffolding effect which captures a greater amount of air to more efficiently trap body heat.
The structure also creates UltraPeak’s resilient loft and exceptionally soft hand, resulting in a similar look and feel to down. The ability to accomplish down-like performance and loft with a batted insulation structure is a game changer in the world of synthetics and UltraPeak’s ease of use compared to loose-fill insulations provides the additional benefit of manufacturing efficiency for brands developing high-performance outdoor garments.
UltraPeak is also manufactured using the company’s proprietary PURE – Produced Using Reduced Emissions – renewable manufacturing technology, which can reduce carbon emissions by up to 70%.
In the development of PURE, Primaloft specialists looked carefully at materials, product design and the production process itself. The proprietary technology takes a holistic approach that perfectly matches materials, engineered recipes, equipment and energy production to reduce carbon emissions compared to traditional production methods still widely used throughout the industry.
The company is increasingly transfering production to its PURE system.
“The development of UltraPeak is backed by our deep understanding of the needs of outdoor enthusiasts,” said Anne Cavassa, CEO of PrimaLoft. “This technology sets a new benchmark for the industry.”
