The materials used to make high-quality rainsuits provide waterproof and breathable protection from the elements. These materials typically include durable nylon, polyester, or polyurethane that is treated with a water-repellent coating. Other features like taped seams and water-resistant zippers further enhance the suit's ability to keep you dry.

When selecting a rainsuit, consider the protection level you require. Jackets and pants with higher waterproof ratings provide better protection against heavy downpours, while lower ratings may suffice for light rain. Also, assess the breathability of the rainsuit if you anticipate engaging in activities that can cause you to sweat. Look for features like pit zips or breathable materials to enhance ventilation.

Essential features to look for in a rainsuit include a hood for head protection, adjustable cuffs and hems to keep water out, and pockets for storage. Additionally, consider the type of closure the rainsuit offers. Zippers provide easy access, while button or snap closures offer better protection against water penetration.

Properly caring for your rainsuit ensures its longevity and effectiveness. After use, rinse it with clean water to remove dirt and salt. Avoid using harsh detergents or bleach, which can damage the water-repellent coating. Air-dry your rainsuit, avoiding direct heat or sunlight. Periodically reapply a water-repellent treatment to maintain its waterproofness.
