As its name suggests, down is made up of the finest, softest, lightest, and fluffiest feathers that there are, giving it exceptional properties and a guarantee of high quality. A fibre with remarkable loft and impressive thermal capabilities, down forms clusters of small filaments that trap air, allowing it to hold in heat.
Compared to other natural insulators like wool, down offers a better heat-to-weight ratio. Appreciated in activewear for being breathable and highly compressible, down clothing has won over our daily wardrobes.
