This rain jacket requires no assembly or complex setup; simply put it on and adjust the zip as needed. It is compatible with a wide range of outdoor and activewear, designed as an outer layer. Its standard fit accommodates typical layering underneath. For `care`, it is recommended to wash the jacket according to the label's instructions, typically a `machine wash cold` with similar colors and `tumble dry low`, to maintain its water-repellent properties. `Avoid bleach` and `ironing`, as these can damage the fabric and its protective coating. Over time, the water repellency may diminish; consider using a specialized DWR (Durable Water Repellent) wash-in or spray-on treatment to restore its performance.
