Groundsheet
Overview
A groundsheet is a protective layer placed beneath a shelter floor to reduce abrasion, moisture transfer, and long-term wear.
Key points
- Made from materials such as polyethylene, silnylon, Dyneema composite, or repurposed plastic sheets.
- Used with tents, tarps, and some bivy systems.
- Helps protect against sharp objects, mud, and pooled water.
- Weight and durability vary significantly among materials.
Details
A groundsheet acts as a barrier between the shelter and the ground, extending the life of the shelter floor while improving comfort in damp or abrasive environments. Ultralight hikers may trim groundsheets to minimal dimensions to reduce weight, while others prefer heavier, more durable options for rough terrain or long-term use.
