    20 Deniers: Unit of measurement used to express the thickness or fineness of individual fibers in a fabric. 20 denier indicates a very thin and light fabric.

    400 Thread Count: Indicates that there are 400 threads per square inch in the fabric which translates into a denser/stronger, finer and potentially softer fabric.

    Filling: 160 g of 90/10 850 CUINS duck feather with Non Live-Plucking certificate

    Feather is a natural product and therefore it is normal to have some dark groups of feathers orclusters inside the jacket, even in the whitest feather. In OS2O we prefer not to bleach them with bleach as it is tremendously harmful to the environment. This is why, in some cases, small dark areas inside the garment can be seen that in no way affect its performance.

    Muy sorprendido con el plumas además de ligero es muy confortable, abriga bastante y tiene dos puntos a favor primero la segunda manga y segundo el cuello alto que abriga hasta prácticamente la boca. yo lo recomiendo, la entrega super rápida.
