If you need extra durable and reusable sandbags that are built to last you got to try these out! Whether you are using them to control erosion or hold down tarps or signs, our Polyethylene Mesh Sandbags (also called monofilament sandbags) will get the job done.

They last 2-3 times longer than traditional polypropylene sandbags and have a weight capacity of 70 lbs! They are UV resistant and can last 1-2 years under direct sunlight in high heat places such as California and Florida. Because they are so heavy duty, you can fill them with rocks or gravel and they won't break.

What kind of sandbags does the military use?

Military Grade Sandbags are made from polypropylene and can last 1,600 hours under the sun.

Which sandbags last the longest?

Generally speaking, polyethylene sandbags last longer than both polypropylene and burlap sandbags. That’s because polyethylene is a heavier duty plastic than polypropylene, while burlap is a natural material that will biodegrade. Sandbags durability depends on other factors such as thickness, edging, how tightly it's woven, and whether the plastic has been treated with a UV resistant additive.

Sandbaggy 14-inch x 26-inch Polyethylene Sandbags, Long-Lasting (1-2 Years) - 70 lb Capacity Review

Current use

I used these to replace yhe old sandbags of 8 months which were deteriorating pretty badly. So far in the Nevada summer sun, it's holding out.

Super product/Prompt shipping

I purchased the 26 X 14 poly bags. I plan to weight down the stairs in my above-ground pool, and provide weight in the bow of my aluminum boat so that it handles better in the wind when I'm fishing. These bags, which are superb quality, are perfect for this. It is essential in both applications that the bags can't rip. These bags are perfect!
