    The 20K FULL ZIPPER pants are designed to be used in intense aerobic activities. We have developed a tailor-made fabric for this garment, following our FAST&LIGHT functional design philosophy. Hand in hand with one of the most important textile manufacturers in Taiwan, we have created an exclusive 2.9 Layer functional fabric for skimo pants, with a resistant 20 deniers 100% nylon outer fabric laminated to a 20/20k polyurethane membrane and the innovative 3D printing as an inner layer which adds extra protection to the membrane and resistance to the fabric and allows you to have the functionality of a 3-layer fabric in the weight of a 2.5-layer one.

    For O2 membranes - 2.9 layers follow these recommendations:

    1. It is important to wash the garment regularly, especially after having been used in an intense aerobic situation with sweat, or after having been exposed to any chemical substance that could affect its properties.

    2. Wash the garment alone or with other breathable waterproof garments. Wash the right side item.

    3. Machine wash (never hand wash) in cold water at 30ºC.

    4. Do not use fabric softeners.

    5. Use liquid detergent, forbidden to use bleach, avoid powder detergents.

    6. To increase the duration of the garment and its properties, we recommend the use of specific Nikwax® products

    7. Rinse several times (at least two rinse cycles) if necessary: although it may seem strange, the garment should not smell of soap.
