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 Free Duo and Free Trio 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.

Dyneema® Composite Fabric is composed of high strength Dyneema® fiber laminated inside a polyester membrane. It is inherently waterproof and does not require any coatings or DWR treatment. Dyneema® Composite Fabric has very high tensile strength for its weight and does not stretch.

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.

 104 lb/in (911 N/5cm)

Puncture Strength: 3.5 lb (15.5 N)

Water Resistance: 20,000 mmH₂O

High quality and ultralight sheet!

Was using tyvek but decided to upgrade to dyneema for a smaller pack size. Very happy with purchase! No complaints - high quality and durable as all zpacks products are!

Ground cloth good!

Purchased this for my Duplex XL and love it! It’s so light and I recently used it inside my tent - high winds and really cold temps to increase the warmth of my sleep system! Really light weight and durable so I’d rather wear this out than my Duplex

Great product!

This is a great product and much easier to use than a piece of plastic. If you have the money, I highly recommend it.
