PrimaLoft Takes Aerogel Tech Outdoors

With the introduction of the Cross Core™ Series this Autumn/Winter season, PrimaLoft® is pushing the boundaries of performance. Up to 80% post-recycle content has been used as PrimaLoft continues to its mission to be Relentlessly Responsible™.

This new product platform combines existing PrimaLoft materials with new technologies to provide superior thermal lightweight performance. PrimaLoft has found a unique way to integrate Aerogel material into specific fibres, allowing the development of apparel insulation that’s built to withstand the extreme challenges of outdoor garments.

Originally developed by NASA for use in aeronautical applications, silica Aerogel is a highly porous, low-density structure that forms a temperature barrier which locks out cold and heat. Aerogel is composed of more than 95% air, is the lightest solid material known to man and one of the most effective insulation materials.

Conventional wisdom has always meant that thicker is better, but PrimaLoft continues to push the limits of lightweight warmth – this time with PrimaLoft Gold Insulation with Cross Core™ Technology.

This latest insulation fuses PrimaLoft Gold Insulation performance synthetics with Aerogel technology lightweight thermal protection to reach previously unattainable levels of warmth in various winter conditions. 

It can provide up to 52% more warmth with the same weight compared to PrimaLoft Gold Insulation. This allows wearers to achieve enhanced warmth with less weight. The new insulation also contains 35% post-consumer recycled (PCR) content.

What is PrimaLoft?

PrimaLoft, Inc. is a materials science company and a world leader in research and innovative development of comfort solutions with high performance insulations, fabrics and yarns. PrimaLoft insulation was originally developed for the U.S. army as a water-resistant, synthetic alternative to down.

Today, the brand is recognised as a benchmark in the outdoor industry for providing unsurpassed comfort, active in sustainable textile production through partnerships with the bluesign® system, the International OEKO-TEX® Association and the Sustainable Apparel Coalition’s Higg Index.

PrimaLoft is a polyester microfibre (smallest fibre in the industry). Smaller fibres trap greater quantities of air, resulting in superior thermal performance and a softer hand feel. The fibres are more compressible than other fibres in the industry.

PrimaLoft is water repellent as fibres have a proprietary treatment which reduces the amount of moisture the fibres can absorb, while at the same time changing the characteristics of the fibres so they physically repel water molecules. As the fibres absorb very little moisture, the insulation maintains the highest percentage of warmth when wet. 

In a nutshell PrimaLoft is warmer, softer, drier, more compressible and super lightweight.

    Hello, thank you for your post. I’d like to ask the source of first image. Could you let me know where did you get that image?

    It’s quite hard to get one of these stringent sustainability certifications, like Bluesign, the commitment and the effort required by the company to be certified is massive.
    You can make an impact on the environment and society by purchasing products with sustainability certification labels… it’s always good to remember this.
    Simply, choose and take action!
