PrimaLoft Unveils New Insulation, PrimaLoft UltraPeak

The latest breakthrough reaches new heights, delivering PrimaLoft’s warmest insulation to-date.
Published: October 25, 2025 Press Release

PrimaLoft, Inc., the global leader in high-performance, sustainable insulation today announced the launch of PrimaLoft® UltraPeak™, the pinnacle of performance insulation. It’s the culmination of years of innovation, backed by a heritage of performance advancements. As insulation experts since 1984, PrimaLoft has leveraged its decades of fiber know-how to develop a breakthrough insulation that delivers unrivaled warmth, elevated loft, and a soft hand feel. 

PrimaLoft® UltraPeak™ utilizes special architectural fibers to create a unique framework that more efficiently traps heat, resulting in PrimaLoft’s warmest insulation to-date. In addition to offering unparalleled warmth, UltraPeak™ features outstanding loft and resiliency, as well as a soft hand feel. Staying true to its Relentlessly Responsible™ mission, PrimaLoft® UltraPeak™ is made with 100% recycled content, and PrimaLoft® P.U.R.E.™ manufacturing technology, which reduces carbon emissions during the production of insulation by 50% or greater, compared to traditional methods. 

“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’s unique architectural fibers intermingle with surrounding microfibers to create a scaffolding effect within the insulation structure. This unique fiber framework captures a greater amount of air to more efficiently trap body heat, making it PrimaLoft’s highest-performing insulation. 

The structure also enables UltraPeak’s resilient loft and exceptionally soft hand feel, achieving a remarkably 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. UltraPeak’s ease of use compared to loose-fill insulations provides the additional benefit of manufacturing efficiency for brands developing high-performance garments for outdoor adventurers.

“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 PrimaLoft® P.U.R.E.™ manufacturing technology is the latest step in PrimaLoft’s expedited approach to transitioning its insulation portfolio toward more sustainable production methods, at scale. Starting in January 2025, PrimaLoft converted Gold Insulation to PrimaLoft P.U.R.E, reducing carbon emissions for its flagship legacy product. This kicked off a concerted effort to expand the use of P.U.R.E across PrimaLoft’s insulation portfolio. Additional legacy products will convert in the coming seasons, while UltraPeak™ and upcoming innovative technologies will use P.U.R.E., from the start.
