Polycro Advantages

Ultralight Weight

Affordable Cost

Polycro tops the list due to its affordability. Yes, it is one of the most affordable ground cloths available in the current condition.

All Sizes are Durable

The best part is that you can trim this ground cloth to get the right size without impacting the integrity. Even if it is not the toughest ground cloth, it will last for plenty of uses before it wears down.

Cons of Polycro Materials

It’s not Breathable

Even if Polycro is durable and lightweight, it has some downsides. As it is not breathable much, it can collect condensation and cause discomfort. After using it for a night, you can hang it to dry up. Also, you can lay your ground cloth under the sun. Once it is dried up, you can use it comfortably.

The Material can Shrink

Another downside is that the material can shrink a bit if exposed to heat for a long time. However, you can avoid such a possibility by avoiding constant sun exposure. Also, maintain the Polycro ground cloth properly to boost its durability.

Tyvek is a 100% synthetic material that’s made up of dense polyethylene fibers. It’s known for being lightweight, water-resistant, breathable, and durable.

Advantages of Tyvek

Water Resistant

Compared to Polycro, Tyvek is closer to being waterproof, and perfect for stopping water from entering your tent or other gear.


Another benefit is that it is very breathable considering how waterproof it is. It will not collect condensation if you use it overnight. Apart from that, it will not shrink like the Polycro if left in high heat and can last longer with minimal maintenance.


Tyvek is considered one of the most durable ground cloths, which is why it’s used in so many different industries. Since it’s very durable it does come at the cost of being a little heavier than other Polycro options.

Differences Between Polycro and Tyvek

The biggest difference between the two materials is the cost and weight of both materials. Polycro is one of the cheaper options for ground cloths, and one of the best lightweight materials around.

It’s relatively durable but it does require more work to keep it clean since it’ll most likely get wet overnight.

Tyvek is also affordable, although it costs more than Polycro footprints. It’s pretty heavy compared to other ground cloths, but it works well at staying clean and dry throughout the night.

Polycro vs. Tyvek: The Winner

Polycro is better if:

  • You’re looking for a lightweight and cheaper material
  • The extra maintenance to keep it clean is fine with you

Tyvek is better if: 

  • Durable but heavy material is what you need
  • You’re okay with the loud sound of the material

If you want a breathable, affordable, and durable ground cloth, you can go with Tyvek. It will serve you for a long time. But you should be aware that it is a bit noisy and heavy as well.

However, if you want a lightweight ground cloth, you can go with Polycro. It is lightweight but not breathable. You will have to take extra caution if you choose this option since there’s a chance it could shrink over time.


Now you know the strengths and weaknesses of Polycro and Tyvek you can make the best choice for your situation. Overall, if you want a lightweight cloth, you should consider getting Polycro. For durability, Tyvek will be the better option and will last longer.
