To use this ski suit, simply put it on like you would any regular suit. Make sure to zip it up properly for full protection on the slopes. When it comes to care, it's best to follow the general clothing care rules. You can machine - wash it on a gentle cycle with mild detergent. Avoid using bleach as it may damage the fabric. After washing, let it air - dry to keep its shape. Also, since the knees have some worn marks, be a bit more careful around those areas to prevent further wear and tear.
