Outlast Technologies is showcasing Aersulate Wadding – its NASA-inspired, fiber-based insulation – at PERFORMANCE DAYS Munich on October 29–30, 2025. 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. During the event, the Outlast team will be at Booth L19 to welcome its visitors and present its wide range of applications.
“With our patent-pending fiber technology, Aersulate® redefines what textile insulation can be: thin, light, and powerful,” said Ari Pachur, Senior Business Development Manager Overseas 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.”
Proven performance, sustainable by design
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.
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 and same warmth at up to 35% less volume (no extra bulk)
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.
High performance 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.
