Your tent protects you every step of the way, from harsh rainy nights to dew dropped mornings. Shield your tent floor from unnecessary wear and tear, and add longevity with a flat groundsheet.

Our tent floors are reasonably durable as-is but an extra layer doesn’t hurt for peace of mind.

This is also available as Poncho which also doubles as a pack cover.

  • Constructed from 1.0 oz/sqyd Dyneema® Composite Fabric. The material is waterproof, and and has good abrasion and puncture resistance for its weight.

  • The perimeter has hemmed edges, and there are reinforced stake loops at the corners and at the center of the sides.

  • The dimensions of the flat groundsheets are a couple inches narrower and shorter than the tent floor that it fits to avoid rain water pooling on the groundsheet.

  • Bathtub style groundsheets for use under flat tarps are available here.

  • All Zpacks gear has a two year limited warranty against defects in materials or workmanship. Please see our return / warranty policy.

  • Made in the USA.

1 oz/sqyd Dyneema® Composite Fabric has a thicker membrane giving it more abrasion resistance. We use it for dry bags, tent floors, and groundsheets.

Thumbs Up!

For the little bit of extra weight, this give me extra protection for the floor of my duplex. Can also be used as a tarp in a pinch.
