Icebreaker Quantum Headband
Here's what other sites are saying:
The Quantum headband from Icebreaker is ideal for the winter athlete who needs some warmth around the ears.
To wear the Icebreaker Quantum Headband, you don't have to fully understand how what was thought of as five different string theories turned out to be one string theory. You also don't have to have all 11 dimensions worked out. All you really need is a slightly chilly forehead. Merino wool naturally regulates your body temperature and deals with odor so you can wear this headband day after day during the physics conference (or, more likely, during your ski vacation).
