Details Therm-a-Rest EvoLite Self-Inflating Sleeping Mat The Therma-a-rest EvoLite is a hybrid mat that combines the best features of a foam-filled self-inflating sleeping mat with the lightweight high-loft comfort of an air-filled mattress. AirFrame™ construction adds stability and self-inflation (it just needs a few breaths to fill it with air), and also reduces convection currents within the mat. A ThermaCapture reflective layer traps radiant heat adding even more warmth. Stuffsack and repair kit included.
