I live in Germany and as Ned Stark never got tired of saying: Winter is coming. I ride my bike to work in the morning and back home in the evening. As of right now, my biking gloves manage to keep my hands from freezing.
I'd rather avoid wearing bulky gloves which prevent me from grabbing my keys from my trousers pockets for example .
In terms of heat preservation I remembered glasses with additional layers filled with air to prevent beverages from warming up or cooling down too fast. Could a kitchen glove under my biking glove produce a similar effect?
Are there other suggestions?
