1. Make sure the shell of the coat you want is waterproof or non-waterproof. The naked eye can not see whether the product picture is waterproof can ask customer service or check the clothing material in the details page to ensure that the shell of any coat you choose is marked whether it is waterproof.
2. Choose the right type of insulation. Winter coats come in three types of insulation: down, synthetic fiber and fleece fabric.
3. Look for zippers and cuffs.
4. Receive the coat you like. Check that it is really of high quality. Check the seams to make sure no threads are hanging out. Make sure there are no holes where the fabric has leaked out.
