According to the manufacturer, the insulation is constructed in two parts with 133 g PrimaLoft Gold Cross Core on the back of the hand for maximum insulation and 60 g PrimaLoft Gold Eco in the palm for improved mobility.
In my opinion, the insulation is completely adequate. Only once have my fingers complained about the approaching cold. But that was only the case under difficult weather conditions at -20°C. High-quality goatskin is used for the fingers and palms. This makes the gloves very robust and means that they can be expected to last for many seasons. Part of the thumb is made of rough leather. This can be used to remove moisture from the outer lens of the goggles. A nice detail that can be helpful in one situation or another!
