Testers dubbed this waterproof, windproof Thermolite insulated sack "the warmest of the shelters we tested." They also praised the plyable fabric, which stood up to rock slabs, rough forest ground, and repeated packings; the lightly brushed interior surface; and the Velcro foot vent; which kept condensation to a minimum.
