雨具って英語でなんて言うの？

The best term for talking about items/clothes/gear that can protect you from the rain is called "Rain Gear". There are a lot of different kinds of rain gear that we can use. There are raincoats, umbrellas, rain boots or just normal boots. These can all be very useful types of rain gear that can shelter us from bad weather.

"Wet weather" is another way to describe "rainy weather". "Wet weather gear" may include items such as raincoats, waterproof ponchos, umbrellas, and gumboots. "It rains a lot here, make sure to bring your wet weather gear".

Items of clothing that protect a person from the rain or wet weather are known as 'waterproofs'. These can then be broken down into items of clothing, for example: Waterproof trousers, waterproof coat, etc.

These are the terms for clothes that you wear when the weather is "wet" or "rainy". Such clothes consist of raincoats, umbrellas, wellie boots etc..

Waterproof means it is against water. They can be used to call anything from shoes to coats, Umbrellas are inherently waterproof and so technically they are not blatantly described in shops as waterproof. But jackets and shoes and coats can be waterproof and can not be waterproof as well. Rain protective clothes can also be used but the most common word is waterproof. Rainy clothes also refers to clothes worn when it rains. Hope this helps!

Rainwear is what one is expected to wear when it is raining, usually this is something waterproof which will prevent the water from ruining their clothes.
