UST Fillmatic Sleeping Mat

The mat contains an open-cell foam core that expands when the valve is opened, drawing air inside automatically. While it will inflate most of the way on its own, you may need to add a few breaths of air to reach your preferred level of firmness.

Yes, the Fillmatic XL features a built-in buckle system along the sides that allows you to attach multiple mats together. This is a great feature for couples or families who want to create a larger, unified sleeping surface.

At 18.65 lbs, this mat is designed for car camping rather than backpacking. Its size and weight make it best suited for trips where you are setting up camp near your vehicle.

The mat provides 4 inches of thickness. This substantial profile is designed to keep you well-insulated from the ground and provide a comfortable, bed-like experience.

To pack it, open the valve and begin rolling the mat tightly from the opposite end to force the air out. Once rolled, close the valve to prevent air from re-entering while you secure it for storage.
