Mammut Polartec Power Grid Jackets

Waterproof vs. water-resistant

• A waterproof jacket keeps out hard, driving rain
• A water-resistant jacket can handle light rain for a brief time and is more breathable

Windproof vs. wind-resistant

• Any waterproof jacket is also windproof to shield you in stormy weather
• A wind-resistant jacket will offer much lighter protection

Hard shell vs. soft shell

Like a waterproof and windproof rain jacket, a hard shell will offer the most protection, but less breathability than a soft shell.

Do you need insulation?
For very cold rainy weather, consider an insulated shell, which will have down or synthetic fill for warmth while being waterproof and windproof.
