PrimaLoft® Insulation ThermoPlume® Gains Adopters, Momentum

More outdoor and lifestyle apparel brands are turning to PrimaLoft Insulation ThermoPlume, the sustainable, ethical down alternative, as it delivers on performance and offers a variety of design and style choices for consumers.

LATHAM, N.Y. (January, 2023) – PrimaLoft® Inc., a global leader in advanced material technology, has seen a wave of brand adoptions of PrimaLoft® Insulation ThermoPlume® this winter season.

ThermoPlume is made up of feather-like plumes of synthetic fibers specially designed to mimic the lightweight warmth, loft, softness and compressibility of natural goose down. This enables designers to create garments that check the box for consumers seeking a vegan-friendly alternative that delivers the style and loft of down with the high-performance characteristics of PrimaLoft synthetic insulation.

Its construction allows for it to be blown through traditional down-blowing manufacturing equipment, simplifying the manufacturing process for brands, and allowing product designers the freedom to create innovative garments.

“ThermoPlume is the ethical response for brands looking to achieve the sought-after lofted look in garments, without having to make many changes to internal manufacturing processes already in place.”, states Tara Maurer-Mackay, SVP of Product at PrimaLoft. “It helps to simplify the supply chain, combat the volatility of down prices and provides consumers with peace of mind when it comes to the ethical sourcing of materials.”

The freedom in the design process has made ThermoPlume a popular vegan-friendly alternative for outdoor and lifestyle apparel brands. Today, the series includes three different products:

PrimaLoft® Black Insulation ThermoPlume® – 100% post-consumer recycled content
PrimaLoft® Silver Insulation ThermoPlume® with Cross Core™ technology – fuses our best-in-class insulation fibers with aerogel technology to deliver next-level lightweight warmth.
PrimaLoft® Black Insulation ThermoPlume® Bio™ – uses 100% recycled content and enables synthetic insulation fibers to return to materials found in nature.

In its relentless approach to elevate both sustainability and performance through innovation, PrimaLoft was able to convert both Black-level PrimaLoft ThermoPlume insulations to 100% recycled material while maintaining the same level of warmth and performance. In addition to repurposing existing polyester, using recycled material results in drastic carbon savings compared to virgin polyester.

With more than 70 brand adoptions, PrimaLoft ThermoPlume is one of the best-selling products in the portfolio. For Fall/Winter 2022-2023, key brands include Nike, ALO Yoga, FP Movement, Helly Hansen, Montane, Vuori, Ecoalf and more.

FP Movement utilizes PrimaLoft® insulation in a variety of their products. From studio to street, for hike, dance, running and all workouts in between, FP Movement is designed using signature technical fabrics that reflect the transformative power that is Movement.

“We at the FP Movement Outerwear design team love the function and durability of PrimaLoft product, especially the ThermoPlume fill!” notes April Johnston, FP Movement’s assistant design director. “It is 100% recycled, lofty and warm without weight, as well as extremely packable – which we love for our packable puffer family.”

For more than 25 years, Montane has been providing innovative, lightweight, and breathable clothing and equipment for endurance sports and activities in some of the world’s toughest, most extreme environments.

“We first launched jackets using PrimaLoft ThermoPlume back in 2017, and they have grown into a highly successful product line. For Fall/Winter 2023 we re-introduced our Icarus line, a high-performance jacket made with sustainability in mind. Warmer than the previous model, the unique insulation is a combination of both batted PrimaLoft Insulation and ThermoPlume loose fill, made to look and feel like a down jacket. We have reduced the environmental impact by using recycled materials in the outer fabric, insulation, and lining to align with Montane’s sustainability goals.” – Marc Davies (Product Line Manager) and Liam Steinbeck (Materials Manager)
