Outperforms traditional down and synthetic fills by up to 5× at a fraction of the mass. 1mm thick. Breathable. Stretchable. Hydrophobic. Washable. Easily cut, sewn, or laminated into finished goods: from technical apparel to aircraft component compartmentalization. USA Made + PFAS Free.
Polarthin Ghost uses one of the lightest solid materials known to science. Air is trapped in nano-scale pores, creating a thermal barrier that drastically outperforms traditional lofty insulation (down, synthetic fill, or fleece) inside a 1mm profile.
Five times the insulation per millimeter compared to conventional textile liners. While thicker aerogel fabrics show slightly better total insulation, they do so at significantly greater bulk and weight — a tradeoff Ghost was specifically engineered to eliminate.
Aerogel architecture, engineered:
Hydrophobic, breathable, and stretchable. Polarthin Ghost’s porous aerogel matrix releases perspiration vapor while limiting heat loss, improving thermal comfort in outdoor apparel and performance garments.
Easily cut, shaped, sewn, or laminated into finished goods. Compatible with standard textile manufacturing equipment. Equally suited to apparel construction and to industrial component compartmentalization.
Data backed by independent laboratory testing for thermal resistance, vapor transmission, and washability. Full TDS available on request — typically within one business day.
