Over the years I have experimented with many types of warm beanies (or hats), these have included those made out of woo and various incarnations of fleece. More recently I experimented with Down hats, but I keep coming back to my old favourite red Possum Fur Merino hat, if I recall correctly it was purchased from BPL in 2005 or 6 and whilst I have purchased possum fur hats since, this one has the best close knit weave I have found. It weighs in at 59 gms (about 2 ozs.) and I know that when I put it on it will feel warm and my ears will be grateful.
So if you are in the market for a warm walking, sitting or sleeping hat take a look at possum down but try and locate the tight weave which seems harder to find.
Do you have a favourite warm hat?
