How waterproof is 2000mm tent?
Waterproof ratings are measured in millimetres (mm) and usually fall anywhere from 800mm to 10,000 mm. These figures indicate the amount of water pressure a fabric can withstand. That means a tent with a 2,000mm rating will endure a 2,000mm or two metre column of water bearing down on it before it starts to leak.

What hydrostatic head is considered waterproof?
1000mm
For any fabric to be considered fully waterproof it must be able to withstand the pressure of a column of water 1000mm high without leaking. This is classed as a hydrostatic head rating of 1000.
What is the highest waterproof rating for tents?
Waterproof ratings for tents are measured in millimetres and will usually be between 1000mm (the lowest level considered waterproof) and 10,000mm. The higher the rating, the more waterproof a tent will be. Ratings are measured using a hydrostatic head test but these ratings don’t take into account wind driven rain.

How much rain can a tent withstand?
Beyond 1-inch-per-hour rainfall, the “falling force” of rainfall does not increase substantially, because raindrops break up after reaching a certain size, limiting the force they apply to tent fabric. This force is what can cause water to pass through the fabric and coating.
How long does a tent stay waterproof for?
