The AeroGraph Puffer Jacket is engineered to excel in temperatures ranging from -20°C (-4°F) to +20°C (68°F), thanks to our innovative Weather Adaptive Insulation™ technology. This aerogel-based insulation dynamically adjusts in real-time to changing temperatures. Featuring just 160 grams of graphene-integrated fill and a bio-based shell, the jacket delivers exceptional performance without the bulk.
