Riding High HSR (horse-saddle-rider) pads use patented Therm-a-Rest® technology for exceptional comfort and fit. Therm-a-Rest® pads are self-inflating.
The HSR self-inflating pad is comprised of an open-cell foam core and an airtight fabric shell with valve. When you open the valve, the open-cell foam core expands, inflating the pad passively as it pulls air to the inside. Once inflated, you can adjust the firmness with additional breaths, or by letting air out.
