UST Freestyle Sleeping Mat

The stuff sack features a valve that connects directly to the sleeping mat. You simply fill the sack with air by opening it, seal the top, and roll or squeeze the air into the mat, repeating the process until the pad is firm.

The body-mapped baffles are designed to provide targeted support, but as an ultra-lightweight mat, it prioritizes weight savings over plush cushioning. If you are a side sleeper who needs significant loft to prevent hip pressure, you may find it firmer than a traditional air mattress.

This mat is engineered primarily for three-season backpacking and lightweight travel. It lacks the heavy insulation required for cold-weather or winter camping, so it is best used in mild to warm conditions.

At 8 inches by 4 inches, the packed mat is roughly the size of a standard 1-liter water bottle, making it very easy to slide into the side pocket or main compartment of most backpacking packs.

Yes, like most inflatable backcountry gear, it is recommended to carry a small patch kit in case of punctures. Check your specific packaging, but generally, UST includes basic repair materials for field fixes.
