While it's technically possible to wear a normal jacket for skiing, it's not recommended.
Skiing requires specialized clothing that is designed to keep you warm, dry, and protected from the elements.
Normal jackets are generally not suitable for skiing because they lack the features and materials necessary for optimal performance in winter sports.
Ski jackets are typically waterproof or water-resistant, insulated for warmth, and have a variety of features such as snow skirts, adjustable cuffs, and hoods designed to fit over helmets.
They are also designed to be breathable to help regulate body temperature during high-intensity activities like skiing.
Normal jackets may not provide the same level of protection from the cold and moisture, and they may not have the same range of motion required for skiing.
In summary, while you can technically wear a normal jacket for skiing, it's not recommended.
It's much better to invest in a specialized ski jacket that will provide the necessary features and protection to keep you comfortable and safe on the slopes.
