Sibley's groundsheet is both water and vapor impenetrable -- preventing even fine particle soil moisture and condensation from entering from below.

The importance of a solid tent floor is often overlooked. While the canopy of a tent repels rain, wind, and snow, the floor is equally important in keeping you and your stuff warm and dry. Most tents don’t stand a chance against standing water, squishy mud, sharp rocks, or pooling snowmelt. The ‘bathtub style’ groundsheet on the Sibley Ultimate, Pro, and ProTech series rises 4¾ inches (12cm) up the side wall of the tent, creating a waterproof basin to keep you dry in all but the worst of conditions.
The Sibley Tent’s signature groundsheet is a game changer for campers committed to camping comfy in any weather.
