A new insulation technology that represents a viable synthetic alternative to natural down. The innovative ThermoPro filling uses specially constructed fibers to simulate down construction, delivering comparable heat retention properties.

Lightweight, high loft, and quick-drying for effortless efficiency in cold and wet conditions.

ThermoPro is a hollowfibre loose fill designed to mimic the performance of down. Filling the garment with loose fill rather than sheet adds flexibility & packability and the added loft creates more air pockets for a more thermally efficient insulation. Made from 100% recycled polyester, synthetic fills have the advantage over down in that they can cope much better with wet conditions and maintain some insulation even when fully saturated. They are much easier to dry and also to launder when needed.
