    Down is a natural product and therefore it is normal to have some dark groups of feathers or clusters inside of the jacket, even with the whitest down. In OS2O we prefer not to bleach them 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.

    brutal relación entre calor, peso y plegabilidad. No ocupa nada, No pesa nada pero abriga mucho. Ideal para Reuniones o actividad de baja intensidad.

    Los acabados, los tejidos, cremalleras....se nota una prenda de calidad top por los cuatro costados. Aunque tiene un precio alto, la verdad es que la relación calidad/precio sigue siendo muy positivo.
