Made with original 9500-100% Nylon Lucretia yarn, our top-tier original version follows the same materials as the original. As is well known, the original version uses 80% white duck down. Loft refers to the volume in cubic inches occupied by one ounce (30 grams) of down under certain conditions. For example, if one ounce of down occupies 500 cubic inches, the loft is said to be 500. Therefore, we can simply understand it as: loft is the volume of down, and the volume of down is loft. The higher the loft, the more air layer the down can hold for insulation with the same fill power, resulting in better warmth.
