Combining outstanding comfort, value and packability, the Women's Trail Lite makes the perfect companion for your next backpacking or camping adventure. The die-cut premium foam is light and packable while still delivering critical warmth at camp. The 1. 5-inch (3. 8 cm) pad boasts a 4. 5 R-value for year round comfort. The versatile self-inflating pad features the high-performance WingLock valve, which has three times the airflow rate of the classic valve thanks to a larger opening and one-way inflation.
