Outlast Technologies is showcasing Aersulate Wadding – its NASA-inspired, fiber-based insulation – at PERFORMANCE DAYS Munich. Recognized among the Top Ten in the show’s Innovation Forum, Aersulate was selected from over 2,000 fabric submissions, standing out to the jury for its high thermal efficiency with low volume.

At the core of Aersulate is aerogel – the world’s lightest solid, consisting of up to 99% air. Outlast embeds an impressive 50% by volume of aerogel directly into viscose fibers, creating an insulation that is exceptionally light yet extraordinarily effective.

Outlast Technologies is presenting Aersulate Wadding—NASA-inspired insulation made from viscose fibers embedded with 50 per cent aerogel by volume—at Performance Days Munich.
Named among the show’s Top Ten innovations, it delivers up to 37 per cent higher thermal efficiency and maintains warmth even under compression.
Aersulate offers a sustainable, animal-free alternative to down and synthetic fills.

Proven Performance

Independent lab data confirm a significant increase in thermal efficiency versus conventional solutions:

• +35% higher RCT values in wadding
• Up to +37% higher RCT in needlefelt applications
• Same warmth at up to 35% less volume (no extra bulk)

Performs Under Pressure

Aersulate Wadding delivers warmth precisely where traditional wadding loses effectiveness – under compression. Air is an excellent natural insulator, but in conventional fills it is squeezed out when pressure is applied (e.g., kneeling or sitting), causing thermal performance to drop. With an exceptionally high aerogel content – 50% by volume – Aersulate stores air within a stable, porous microstructure that keeps it from escaping. The result is consistently high insulation – even under compression and in humid conditions. From outerwear and ski apparel to technical workwear, Aersulate reliably sustains thermal performance.

Sustainable by Design

Aersulate Wadding unites aerogel made from quartz sand with renewable, wood-based viscose to offer a sustainable, animal-free alternative to down and conventional synthetic fills – with no compromise on performance.

“With our patent-pending fiber technology, Aersulate redefines what textile insulation can be: thin, light, and powerful,” said Ari Pachur, Senior Business Development Manager Over-seas of Outlast. “Being selected for the Top Ten out of more than 2,000 entries at PERFORMANCE DAYS is a fantastic recognition of what this technology enables.”

Functional Fabric Fair, powered by PERFORMANCE DAYS, has announced its new educational Day 0 Sustainability Workshop and Expert Talks program for the Fall 2025 edition, taking place November 11–13 at the Oregon Convention Center in Portland, Oregon. The expanded event features a dedicated sustainability workshop and comprehensive Expert Talks series, addressing crucial developments in the outdoor and active textiles industry.

Functional Fabric Fair will kick off on November 11 with the return of the Day 0 Sustainability Workshop, sponsored by Hyosung, a full day paid conference program open to both exhibitors and professional attendees. New this year, Day 0 will be held in the Deschutes Ballroom at the host hotel, Hyatt Regency Downtown Portland, located across the street from the Oregon Convention Center. The program will include breakfast, lunch and a networking happy hour beginning at 4:00pm.

Functional Fabric Fair Fall 2025 introduces an expanded educational lineup, including the Day 0 Sustainability Workshop sponsored by Hyosung.
The event focuses on circularity, supply chain decarbonisation, and textile-to-textile recycling.
Over 350 sustainable suppliers and 15+ expert-led sessions will highlight solutions for a more transparent, compliant, and sustainable textile future.

Curated and facilitated by Jill Dumain of Fractal CSOs, Todd Copeland of Copeland Consultancy LLC and Kevin Myette of bluesign technologies, the full-day workshop will bring together industry leaders and sustainability practitioners for new sessions shaped by attendee feedback.

Day 0 Sustainability Workshop topics will include:

• Innovator’s Panel
• How to Scale New Technologies
• Supply Chain Decarbonization
• Circularity (e.g., Textile-to-Textile Recycling)
• Understanding Risks of Forced Labor
• Evolving Regulations and New Legislation
• Supply Network Complexity

Expert Talks education and focus on textile-to-textile recycling

The 2025 edition will spotlight Textile-to-Textile (T2T) Recycling – The Role of Recyclers. With regulations such as Extended Producer Responsibility (EPR) making circularity essential, T2T is emerging as a solution that preserves material quality to create new garments from old ones. Europe is leading progress with upcoming textile collection mandates and innovations in sorting, digital passports and recycling systems.

The exhibition hall will be open November 12–13 and will feature the Expert Talks, sponsored by CovationBio Sorona. The program will include more than 15 educational sessions, free for all attendees, covering topics such as textile recycling, bio-based materials, supply chain collaboration, tariffs updates, microplastic solutions, human rights protections and industry trends.

Expert Talks highlights include:

Wednesday, November 12

• PERFORMANCE COLORS by Nora Kuehner – Update Summer 2027 | Kickoff Winter 2027*28
• Focus Topic – Textile-to-Textile: The Role of Recyclers
• The (Chemical) Additives Panel

Thursday, November 13

• From Imposing to Inclusion: Rethinking Human Rights Protection in the Supply Chain
• Tariffs and Evolving Trade Policies and their Impact on U.S. Apparel Sourcing

“This edition’s expanded educational programming reflects the textile industry’s urgent need to address sustainability, circularity and compliance challenges head-on,” said Steve McCullough, Event Vice President of Functional Fabric Fair. “By bringing together leading experts and practitioners with all new programming, Functional Fabric Fair provides attendees with actionable insights and strategies to shape the future of performance textiles.”

In addition to education, the exhibit hall will feature over 350 sustainable-certified suppliers showcasing functional fabrics, finishes, trims and accessories for the 2026/2027 fall seasons.
