Outlast Technologies has earned a significant industry honour for its new Aersulate® Wadding. The NASA inspired, fibre-based insulation was named a Top Ten product at the PERFORMANCE DAYS Innovation Forum in Munich. A jury selected Aersulate® from a competitive field of over 2,000 fabric submissions, recognizing its high thermal efficiency and low volume.

The core of the technology is aerogel, the world’s lightest solid material, which consists of up to 99% air. Outlast’s patent pending process embeds an exceptional 50% of aerogel by volume directly into renewable, wood based viscose fibres. This creates an insulation that is extremely lightweight yet highly effective. Independent lab tests confirm it delivers up to 37% higher thermal efficiency (RCT values) compared to conventional solutions.

Aersulate® Wadding’s key advantage is its performance under compression. Traditional insulation loses warmth when pressure is applied, as the insulating air is squeezed out. Aersulate® traps air within a stable microstructure, ensuring consistent thermal performance even when sitting or kneeling. The material offers a sustainable, animal free alternative to down for outerwear, ski apparel, and technical workwear.
