The outdoors are meant to be enjoyed, year-round, regardless of frigid temperatures or wet weather. For more than four decades, PrimaLoft has been dedicated to developing high-performance insulation technology that powers your favorite gear, keeping you warm, comfortable and safe, even in the harshest conditions. PrimaLoft’s latest breakthrough, UltraPeak™, establishes a new pinnacle of performance insulation.
PrimaLoft® UltraPeak™ has been developed to achieve the brand’s warmest insulation, to date. In addition to unrivaled warmth, a unique construction also delivers elevated loft and an exceptionally soft hand feel. The breakthrough is a recipe featuring special “architectural fibers.” These distinctive fibers support an internal framework that captures a greater amount of air, more efficiently trapping body heat to keep you warm as the temperature drops. This structure also enables UltraPeak’s resilient loft and soft hand, achieving a remarkably similar look and feel to down, while offering the thermal efficiency, moisture resistance, and durability that PrimaLoft synthetic fibers are known for.
“UltraPeak is dedicated to the relentless,” said Andrea Paulson, Senior Vice President of Technology and Innovation at PrimaLoft. “By rethinking fiber architecture, we’ve developed an insulation that meets the performance standards that the most discerning outdoor adventurers expect when they’re performing at their peak.”
UltraPeak™ also exemplifies PrimaLoft’s Relentlessly Responsible™ commitment to elevating both performance and sustainability. Its breakthrough performance benefits are achieved using 100% recycled content and the company’s P.U.R.E.™ (Produced Using Reduced Emissions) manufacturing technology – a process that reduces carbon emissions by 50% or more compared to traditional production methods.
“At PrimaLoft, we’re redefining the standards for insulation,” said Anne Cavassa, CEO of PrimaLoft. “The development of UltraPeak is backed by our deep understanding of the needs of outdoor enthusiasts and our commitment to protecting the outdoor spaces we all love. This technology sets a new benchmark for the industry and underscores our Relentlessly Responsible mission to deliver responsibly made products that push the boundaries of performance.”
Developing UltraPeak™ using P.U.R.E.™ is the company’s latest step towards transitioning its insulation portfolio to more sustainable production methods. Earlier this year, the company converted its flagship legacy product, PrimaLoft® Gold Insulation, to P.U.R.E. technology. This is just the beginning, with plans to implement P.U.R.E. across PrimaLoft’s insulation portfolio, in the coming seasons. UltraPeak, as well as upcoming innovations, will be made using P.U.R.E., from the start.
UltraPeak’s ability to accomplish down-like loft, softness and appearance using a batted insulation structure is a real game changer in the world of synthetics. Compared to loose-fill insulations, UltraPeak’s batted construction comes with less design restrictions and more manufacturing efficiencies, providing brands with the flexibility to design a wide range of outerwear.
Whether you’re embarking on an arctic expedition or simply preparing for the cold winter ahead, PrimaLoft® UltraPeak™ is the pinnacle of performance insulation. UltraPeak is available now to brand partners, with retail availability anticipated for the FW ’27 season.
