The standard version of the Cloud 6 is not waterproof. However, there are special versions such as the Cloud 6 Waterproof, which is equipped with a waterproof membrane.

As no specific variant (e.g. waterproof) is specified in your product data, your model is probably the standard version, which is not waterproof.

If you are looking for a waterproof version, look for the word "Waterproof" in the product name.
