Iowa Rice Sock Trick for warmth:
Heat a sock of brown rice for 3 minutes in a Microwave to provide 40 minutes of heat in your coat to Winter commutes (also keeps lunch warm in messenger bag). Also makes great neck warmer for watching those bike movies!
A cyclist's wife gave me a professional massage two Winter's ago. She brought a long athletic sock full of brown rice (sewn at the open end) over and threw it into the Microwave for three minutes to warm her hands so that it would not be a shock to my sore neck muscles… she later gave me the sock for my neck to support it while watching TV.
This simple sock heated for 3 minutes at high and place between a rain shell and a sweater turns a cold ride into a near dry sauna experience even at - 7 degrees F with high winds… lasts for about 40 minutes and also feels good around the neck after the ride. Worth a try if you have no Winter riding jacket or left your Assos jacket it at the Tavern!
--you may want to use a dark colored sock though or one that has a football team or other logo in case this object becomes lost! It can be used over and over again. Add Lavender or another aromatic if you do not like the smell or brown rice!
