Quick answer
To protect your dome tent floor, use a footprint or groundsheet that is slightly smaller than the tent floor, and always clear the ground of sharp objects before pitching.
Why a footprint matters
The floor of a dome tent is often the first part to wear out. Stones, twigs, and thorns can puncture or abrade the fabric, leading to leaks and costly repairs. A footprint—also called a groundsheet or floor saver—acts as a sacrificial layer between the ground and your tent floor.
A properly sized footprint extends the lifespan of your tent by absorbing the wear and tear that would otherwise hit the floor directly. It also makes cleanup easier and adds a small layer of insulation.
Sizing: why smaller is better
One common mistake is choosing a footprint that is exactly the same size as the tent floor or even larger. If the footprint extends beyond the tent, rainwater can collect between the footprint and the floor, creating a puddle under your tent.
A footprint that is slightly smaller than the tent floor prevents this problem. Rain that falls on the footprint will run off the edges instead of pooling underneath. This is why the FLOORSAVER SKYROCKET III DOME is designed to be smaller than the tent floor it protects.
Decision rules for choosing a footprint
- Match the tent model: Choose a footprint designed for your specific tent model, like the FLOORSAVER SKYROCKET III DOME for the SKYROCKET III DOME. This ensures the shape and size are correct. Check the tent model number before buying.
- Size it smaller: If you buy a generic groundsheet, cut it so it is 2–3 inches smaller on each side than the tent floor. This prevents water pooling between the footprint and the floor. Measure your tent floor first.
- Use on all ground types: Even on grass, use a footprint. Roots, pine needles, and small stones can still damage the floor. On rocky or thorny ground, a footprint is essential. Don't skip the footprint on soft ground.
