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 stake loops at the corners and at the center of the sides.

  • Groundsheets for our freestanding tents feature elastics with loops at the corners allowing for the groundsheet to be attached to the tent poles at the corners of the tent.

  • 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.

Flat ground sheet

Firstly, I love all your products. The only issue I have is the photo does not match the shape of the ground sheet.

Good backup!

I don't use a groundsheet with my Plex Solo, but having this super light groundsheet just in case the ground looks stabby is worth bringing since it's so light and packs tiny!

Awesome Groundsheet

It's reaaaally light and it has the perfect size. We used it while backpacking as a improvised mat for having lunch and resting, also as a tarp for our gear.... and as a groundsheet for extending the live of our tent.
