Pairing essential 3-season comfort with lightweight packability, the Therm-a-Rest ProLite Apex self-inflating sleeping pad offers top-notch performance for backpacking.

  • Features

    • StrataCore™ construction uses a continuous layer of thermal foam nestled between alternating ridges of air and foam to yield an excellent warmth-to-weight ratio
    • This pad has an R-value of 3.8, which makes it best for adventures in cool weather; it provides moderate insulation from ground temperature
    • Most sleeping pads we sell range from 1.0 (good for warm weather) to 5.5+ (for use in extreme cold); the higher the R-value, the more insulated the pad
    • Expanding foam core self-inflates—simply top off with a few breaths for personalized firmness on 2 in. (5 cm) of StrataCore loft
    • Packs down small to easily find a place in your pack during fast-and-light adventures
    • Intuitive and dependable WingLock™ valve maximizes airflow for easier inflation and quicker deflation; wings toggle for 1-way inflation to save breath
    • A range of sizes allows you to pick a length/width that best suits your adventure needs
    • Stuff sack included
