Supreme Microloft is Fjällräven's own insulation material and one of the leading synthetic paddings for outdoor products. The combination of thin and slightly thicker microfibres produces a fluffy material that fills the garment or sleeping bag with an insulating layer of air.
Just like other synthetic paddings, Supreme Microloft can withstand an amount of moisture without its insulating capacity being significantly impaired. This makes Supreme Microloft an excellent choice for a wide range of outdoor activities all year round – particularly in environments where the jacket or sleeping bag is exposed to rain, splashes or condensation, or in climates where the precipitation alternates between rain and snow.
Supreme Microloft does not provide the same warmth as down (if you compare a product with the same amount of padding of each material) and takes up a little more space when packed up. However, the synthetic fibres are more durable and retain their fluffiness better after compression and extended use. Supreme Microloft is also easy to wash and dry.
