Quick Answer
Yes, there are differences in waterproof ratings for rain gear, with various standards and ratings used to measure the water resistance of fabrics and garments.
Understanding Waterproof Ratings
When shopping for rain gear, it’s essential to understand the difference between various waterproof ratings. The most common standards used to measure water resistance are the American Society for Testing and Materials (ASTM) rating and the International Organization for Standardization (ISO) rating. The ASTM rating measures the water resistance of fabrics using a standardized test procedure, where the fabric is exposed to a controlled amount of water pressure. The ISO rating uses a similar test, but with slightly different parameters.
Rain Gear Ratings Explained
In general, rain gear with a waterproof rating of 10,000mm or higher is considered suitable for heavy rain and waterproofing. Some popular rain gear ratings include:
- 1,000-5,000mm: Suitable for light rain and splash protection
- 5,000-10,000mm: Suitable for moderate rain and wind
- 10,000-20,000mm: Suitable for heavy rain and prolonged exposure to water
- 20,000mm or higher: Suitable for extreme weather conditions and heavy water exposure
Choosing the Right Rain Gear
When selecting rain gear for hunting, consider the environment and weather conditions you’ll be facing. If you’ll be in a heavy rainforest or mountainous terrain, look for gear with a high waterproof rating (20,000mm or higher). If you’ll be in a more open environment with moderate rain, a mid-range rating (5,000-10,000mm) may be sufficient. Additionally, consider the breathability and moisture-wicking properties of the fabric to ensure you stay dry and comfortable during your hunt.
