Microfill Super-Therm is an advanced synthetic insulation used in sleeping bags, praised for its durability and wash resistance. According to the manufacturer, the material retains its full thermal properties even after ten full washing cycles, including spin drying. The fibers remain unchanged in both thickness and length.
Sleeping bags with this insulation typically weigh around 850 grams and are suitable for summer to three-season use. They offer comfort at approximately +8 °C, limit comfort at +4 °C, and survival at temperatures down to -10 °C.
As with most synthetic insulation types, it is recommended to store the bag uncompressed for prolonged durability and optimal performance.
