Thinsulate vs Heatkeep for glove lining
Jan 07, 2015·I believe Heatkeep is Kinco's own insulation for their winter gloves. It does a pretty good job down to about 15deg. and colder if I'm more active. Some wool liners keep me plenty warm most days. I bought some Free The Pow gloves with 200g thinsulate lining and so far my fingertips have been cold almost every time out, except when very active.
