20ft x 20ft Green Canvas Tarp 12oz Heavy Duty Water Resistant

In this review of the 20' x 20' Green Canvas Tarp, the bottom line is simple: this tarp is for anyone who needs a large, heavy duty cover that holds up to sun, rain and snow without feeling flimsy. The finished 20 ft by 20 ft size and 12 oz polyester material give it real substance, and the double stitched seams add confidence when it is tied down or stretched over a frame. Customers cite durability and waterproof performance most often, so this review focuses on real-world handling and long-term reliability.

Key Features

• Finished Size: At 20 ft by 20 ft it covers large areas, making it practical for gear storage, patio shade or temporary shelter.
• 12 Oz Polyester Material: The heavy 12 oz weight provides a sturdy feel that resists tearing under moderate stress and maintains shape in wind.
• Olive Green Color: The subdued green blends into outdoor spaces and offers sun protection while reducing glare underneath.
• Water Resistant and Breathable: It sheds rain effectively while allowing some breathability to limit trapped moisture under the cover.
• Double Stitched Seams: Reinforced seams improve longevity and reduce the chance of seam failure where strain concentrates.
• Gusset Rings and Tie Points: Heavy duty attachment points let you secure the tarp tightly without pulling out the hardware.

Who It's For

This tarp is best for homeowners, landscapers and DIYers who need a reliable, sizable cover for equipment, firewood, outdoor events or temporary shelter. It suits users who prioritize durability and water resistance over an ultra-lightweight packable tarp.

It is less appropriate for backpacking or minimalist camping where low weight and extreme packability matter, and those needing a fully waterproof fabric for prolonged immersion should consider purpose-built waterproof shelters instead.

Pros & Cons

Pros

• Well-constructed with heavy 12 oz material and double stitched seams that stand up to repeated use.
• Generous 20 ft x 20 ft coverage provides excellent value when covering large items or areas.
• Water resistant performance keeps gear dry beneath the tarp in rain and light snow.
• Olive green color offers discreet sun protection and blends into outdoor settings.

Cons

• At 12 oz material weight, it is not ideal for situations where a lightweight, highly packable tarp is required.
