Overview
A 10x20 foot tarp at 16 mil thickness with a thickened PVC waterproof layer under the polyethylene, brass grommets every 23.6 inches, and a poly rope stitched hem. Winpull markets it in green, aimed at year-round outdoor coverage rather than a one-off job.
The added PVC layer over standard polyethylene is what separates this from a plain poly tarp of the same mil rating, intended to add waterproofing beyond what the base material alone provides. At 10x20 feet and 16 mil it covers the same scale of job as other large tarps here, vehicles, boats or roofs, with brass grommets chosen specifically to avoid rust over repeated exposure.
- 10x20 feet, 16 mil, 8 oz per square yard
- Thickened PVC waterproof layer
- Brass grommets every 23.6 inches
- 15x17 weave count
Who it's for
Fits anyone who needs a large tarp to stay outdoors through multiple seasons, covering a vehicle, boat, pool or roof. Not the right pick for a single short trip or a small item, where the size and reinforcement go unused.
Pros and cons
- PVC layer adds waterproofing beyond standard poly
- Brass grommets resist rust over long-term outdoor use
- 10x20 feet covers large items or vehicles in one sheet
- Large size makes it heavy and harder to fold or store
- Green color may not suit every use case
Performance notes
The thickened PVC layer sits between the woven poly core and the outer surface, adding water resistance beyond what a single-layer poly tarp provides at the same mil rating, the detail that matters most for a tarp meant to stay outside through rain and snow. The stitched poly rope hem running the full length of each edge resists tearing under wind load better than grommets alone would.
