I usually make due with a merino/Alpaca beanie(it pulls/stretches down partly over my ears ) and bandanna wrapped and pulled down over my ears. The bandanna tightened around my ears that way also help keep the beanie stretched down tightly. I like Turtle Fir and Patagonia merino beanies but also have ones made by TNF(100% merino). I also have the hood on my shell/rain jacket to throw into the head warmth mix. I have different wt/warmth beanies that I mix and match w /other apparel set ups. I always think about everything working together that I might have for keeping my head/ears/face warm and the rest of me warm for both in camp and while on the move. For hardcore winter hiking I like a balaclava/sherpa like hat and carry a shell w/ a hood. If doing really short mileage less strenuous winter days and where I'm likely to spend more time in camp than usual I like those BlackRock down beanies. Shug was wearing two of them in MN lately in his vid. From what I saw what he was doing on that trip that worked well for him. I don't particularly like wearing down on my head though when on the move.
