PRIMALOFT, INC, a global leader in high-performance, sustainable insulation has launched PrimaLoft® UltraPeak™, described as the ‘the pinnacle of performance insulation.’ As insulation experts since 1984, PrimaLoft has leveraged its decades of fibre know-how to develop ‘a breakthrough insulation that delivers unrivaled warmth, elevated loft, and a soft hand feel.’
PrimaLoft UltraPeak uses special architectural fibres to create a unique framework that traps heat more efficiently, 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, 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 fibres intermingle with surrounding microfibres to create a scaffolding effect within the insulation structure. This unique fibre framework captures a greater amount of air to trap body heat more efficiently, 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.”
Originally developed for the US Army as a water-resistant, synthetic alternative to down, PrimaLoft is used by over 1000 top global brands across outdoor, sport, lifestyle, home, fish & hunt, workwear and footwear..
