Aersulate Wadding Debuts as High-Efficiency Lightweight Insulation
Aersulate® Wadding earns Top Ten recognition at PERFORMANCE DAYS Munich for its ultralight, aerogel-enhanced insulation technology.
Outlast Technologies is spotlighting Aersulate® Wadding at PERFORMANCE DAYS Munich, where its aerogel-infused insulation was selected among the Top Ten innovations for exceptional thermal efficiency and low-volume performance.
Outlast Technologies is presenting Aersulate® Wadding—its advanced, NASA-inspired fiber-based insulation—at PERFORMANCE DAYS Munich. The material earned a place in the show’s Top Ten Innovation Forum, chosen from more than 2,000 fabric entries for its strong thermal performance delivered at remarkably low volume.
Aersulate® is built around aerogel, the lightest solid material on Earth, composed of up to 99% air. Outlast integrates an exceptional 50% aerogel by volume directly into viscose fibers, resulting in insulation that is ultra-lightweight while offering outstanding thermal capability.
Verified Thermal Performance
Independent laboratory testing demonstrates the material’s strong efficiency gains over traditional insulations:
- +35% higher RCT values in wadding
- Up to +37% higher RCT in needlefelt applications
- Equivalent warmth with up to 35% less volume, avoiding unnecessary bulk
High Performance Under Compression
Aersulate® Wadding excels especially in scenarios where standard insulation materials typically fail—when compressed. Air is a natural insulator, yet conventional fills lose their trapped air under pressure (such as kneeling or sitting), resulting in reduced warmth. Due to its exceptionally high aerogel loading—50% by volume—Aersulate® maintains air within a stable, porous internal structure that prevents it from being expelled. This ensures consistently high insulation even when compressed and in humid environments. From outdoor and ski apparel to professional workwear, Aersulate® delivers dependable thermal protection.
Sustainability at Its Core
The insulation combines aerogel derived from quartz sand with renewable, wood-based viscose, offering a responsible, animal-free alternative to down or synthetic fills—without any sacrifice in 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 Overseas at 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.”
Experience It Live at PERFORMANCE DAYS Munich
Aersulate® Wadding will be showcased at PERFORMANCE DAYS Munich on 29–30 October 2025 at Booth L19. Visitors can explore the material firsthand, discover why it was chosen for the Innovation Forum’s “Top Ten” feature, and connect with the Outlast team to learn about its broad application potential.
