Footprint Groundsheets are available for most SunnCamp tents with a SIG. Please check the tent listings for full availability. Protect your sewn in groundsheet ('SIG System') with our new 'Made to Measure' Footprint Groundsheets tailored to fit your SunnCamp Tents. These fully eyeleted PE groundsheets sit between the ground and the base of your tent, reducing the chance of puncture while helping to keep the underside of your tent clean. For safety they are also flame retardant.
