Core Tarps Extreme Heavy Duty 20 Mil Tarp Cover 16 x 20 - Silver/Black

Our review of the Core Tarps Extreme Heavy Duty 20 Mil Tarp Cover finds it best suited for homeowners, contractors, and campers who need a thick, weatherproof tarp that delivers on coverage and durability. The single biggest reason to buy is the combination of a true finished size and a heavy 20 mil construction made from 100% virgin polyethylene, which gives this tarp notable weight and tear resistance compared with thinner, recycled alternatives.

Key Features

• Finished Size: The tarp is sold as a true finished 16 ft x 20 ft size so buyers get full stated coverage without inches missing from the edges.
• Virgin Polyethylene: Constructed from 100% virgin polyethylene for improved durability and resistance to rot and premature breakdown.
• Reinforced Edges: Reinforced hems reduce fraying and help the tarp hold shape when tied down or under sustained load.
• Metal Grommets: Metal grommets every 18 in make secure tie-downs easy with rope or bungee cords and distribute stress along the edge.
• Weather Protection: The silver/black tarp is waterproof, UV resistant and designed to stand up to sun, rain and snow for year-round outdoor use.

Who It's For

The Core Tarps 16 x 20 is aimed at users who need large, dependable coverage: people protecting roofs during repairs, covering boats or pools in bad weather, or creating heavy-duty shelter for camping and events. Its weight and reinforced construction are useful where a flimsy, thin tarp would fail.

Those who need ultralight or packable camping tarps, or who require specialized breathable covers for delicate equipment, should look elsewhere. This tarp prioritizes strength and waterproofing over minimal weight or breathability.

Pros & Cons

Pros

• Thick 20 mil material and 100% virgin polyethylene yield a robust, long-lasting cover for tough weather.
• Actual finished dimensions mean buyers receive the full 16 ft x 20 ft area advertised.
• Reinforced edges and grommets every 18 in make fastening secure and reduce tear points under load.
• Good value for protection against sun and rain thanks to UV resistance and waterproofing.

Cons

• Some users report occasional tearing under extreme abuse, so it is not indestructible despite the heavy construction.
• The tarp's weight makes it less convenient to handle and pack for minimalist or ultralight use.
