Read the label on your deck, ATV cover, motorcycle or deck, and very likely to be terms like "waterproof", "resistant water "and" water repellent. "You might think that all mean the same, but the truth is that there is a difference between a water resistant cover and a waterproof cover.

What is the difference between all these terms? Here's how online Merriam-Webster defines:

• Waterproof: "waterproof, especially: covered or treated with a material (as a solution of rubber) to prevent penetration of water "
• Water repellent (also waterproof): "treated with a finish that is resistant but not impervious to penetration water "

Waterproof and water repellent essentially mean the same thing. A waterproof cover is specially treated to resist water, but in heavy rains, water can still happen. Water resistant refers only to prevent water comes through the deck to a certain extent. Your boat or ATV yet can get wet in a downpour.

Secondly, due to the nature of water tight waterproof covering, any condensation that accumulates under the deck stays below deck and potentially can cause moisture damage to the vessel or vehicle.

A breathable fully waterproof cover to protect your boat, ATV, motorized or other vehicle interior and exterior moisture.

Also note that a vessel or motorcycle cover may be more resistant to water than another, depending on the quality of the material and its resistance to water pressure. According to Wikipedia, "the resistance water is measured by the amount of water, in millimeters, which can be suspended above the fabric before the water seeps through. "So the pressure water more than a piece of cloth cover can withstand more likely it is to keep your boat or jet dry in heavy rain or snow.
