Pertex Quantum® is the lightest down-proof by construction fabric available. It is a true featherweight at around 30g/m2 and uses the finest yarns available with the maximum thread count.
Less weight shouldn't mean 'please be careful'. Pertex Quantum® stands its ground. Pertex Quantum® shows the best strength to weight ratio. Tear strength and seam strength are good for its weight and it's soft as silk, with the smallest packing volume of any Pertex® material. Pertex Quantum® withstands the abuse of hardcore use.
