What a waterproof rating indicates
Waterproof ratings are commonly expressed in millimetres and are one reference point when comparing fabric protection. Seams, zips, hood design and garment care also influence real-world performance.
Match protection to the activity
Short periods outdoors and light rain may call for a lightweight option, while long outdoor shifts or frequent rain exposure can justify a more protective construction.
Balance breathability and care
Higher protection is not automatically best for every team. Consider activity level, ventilation and the care instructions that help maintain the fabric finish.
