Thermarest Prolite Apex
This self-inflating mattress packs down small and is warm enough for 3-season camping. It has the new WingLock Valve which maximizes air flow and toggles for one-way inflation, making it easy and quick to set up. The Stratacore foam inside has ridges of air and foam, making the mat more compact when rolled up yet maintaining comfort, warmth and thickness.
Stuff sack included.
